Please do go ahead and attempt to rip me to shreds - it should be hilarious to read. And if you do it using "factual details" it may be the first time you've posted such.

Telling new managers that they shouldn't get an advanced trainer when they can easily do so by spending less than 50k on a trainer who has a starting salary of less then 15k because someone
else might overbid occasionally is bad advice. The fact that other people overbid is really not that important - it only impacts you if you are silly enough to follow along and overbid yourself. So it really isn't a big deal to anyone with a bit of self control and awareness that other people overbid, given the abundance of advance trainers with starting salaries below 15k who can be acquired for less than 50k.
The "advice" you have given in this thread is exactly the type of advice which likely causes new players to struggle and get discouraged. Because it will result in them being unable to train their players as well as they could when it is so easy for anyone to get an advanced trainer with both a low salary and a low bid. Instead you've recommended they get a level 3 (competent) by spending 100-150k. Talking about a discouraging result for a new player - they just way overbid on a getting an inferior trainer. If you are bidding on a level 3 trainer, you should be spending much less than 100k on the bid and getting someone with a salary below 10k. Actually, anyone spending more than the opening 1k bid on a level 3 trainer is overbidding.
I happily learn more about BB most days. Sadly, I've been reading your posts for years and haven't really learned anything from them, nor have I seen any evidence (no, I don't believe your claims about having been an NBBA team) that you have ever been better than a DIV team in the US - not an accomplishment in my opinion. But then again, everyone can set their own goals in this game and if being a low level team which competes against bots to build a fictitious bank account is your goal, that is fine. I'd be somewhat surprised if it is a common goal of most people who join the game however, so giving them advice to land them in your situation is quite likely to frustrate new players.
