Hopefully I can help you out with some of these issues. The key to maintaining interest in franchise is to use a team you are going to have fun with. Maybe that is the team you know the most about, or maybe it is a team in the dumps (I use the Astros to rebuild), or possibly a team with a bunch of young budding stars.. perhaps a tough division. Once you have that team ...
1. Yes adjusting rosters every day is annoying. One thing that can help is to set injury management to MLB only. That way when all those AA and AAA guys get hurt (usually minor anyway) the CPU takes care of it. Also whenever a AA or AAA lineup is messed up just let the CPU fix that as well if you don't want to take the time. I would recommend checking it every once in a while though (maybe not adjusting the order because lets be honest .. who cares if they win .. but perhaps just to make sure your future players are getting playing time).
2. I'm not sure about this because I don't think I get these e-mails that often. You could always set this to auto as well, because in my opinion it is a useless part of franchise. After a season or two you will have enough money to max out all your vendors.. and the pricing thing is always adjusting anyway so auto seems to work.
3. Just pay attention to the high potential guys if you want. And to be honest you really don't have to pay all that much attention to the minors except guys you plan on using in the future. So to take some strain off knowing your whole minor league system just focus on the top commodities you have.
4. Scouting is pretty simple. Scout guys who are 18 years old or higher. The people younger than that won't be in the draft. Beyond that only scout players until you can see their potential and move on to the next. This way you can scout the most player possible (you just have to check back every few days). And yes.. a lot of the guys you draft will suck, but that is probably pretty realistic.
5. This is the one downfall of 30 team control. It sucks going through and picking for each team.. that is that. However doing the auto pick thing (often the highest rated player currently) works, or you could actually check teams weaknesses and draft that way (which takes a while but i do for a while).. Remember not everybody you scout will be in the draft. Lastly it has been said several times that the first draft in franchise has pretty low quality guys.. Also yes you sign those draft picks for incredibly low contracts because often they will be in the minors for a few years before they are MLB ready. You won't come across any Bryce Harper's in the draft unfortunately. However grabbing a couple A prospect guys to develop over a few years is pretty nice. If you want to draft the "bryce harper's of the world" you could always edit their stats to make them "progress" faster.
6. Checking transactions can be a bit annoying, but if you care about the CPU sending the best prospects in the game for a 40 year old closer then 30 team control is a must. You could always turn off trading (under the CPU control set trading to manual) except for a couple weeks before the trade deadline to alleviate checking it every day for the whole season. This will give the CPU a chance to send trade offers but reduce the chance of missing a trade as well as the time spent checking for crappy deals.
7. Development is a season long thing and you don't really see the results week by week. I change training assignments once a month and sometimes if you go to manage roster you can see what stats are improving (+). I don't know that call ups and send downs are all that important. I do them, but i don't have a big strategy behind it. If looking it over every two weeks works for you then that probably will work out fine.
8. It does seem that big name guys are always on the trade block which is weird. I have a feeling the Angels will never trade Pujols yet he is on the block every year. Poor logic I suppose. I rarely look at the trade block. I look through and find players I want. Then to keep it true to life I post it either in the
trade discussion thread on here (usually a pretty quick response) or the
OS Arbitration Panel where people are assigned specific teams to "trade for"
I hope this helps you a bit or at least gives you some kind of direction. I personally think 30 team control is a must because it kills me to see great prospects traded for some over aged over performing guy just because the team is trying to make the playoffs. Does that happen? Yea, but when MLB teams do it in real life the value they get back is much higher. However if you don't care about all that then try a franchise with single team control as this will probably make the draft a bit more tolerable for you.
Good Luck!
