I posted this on EA's forum just now. This is my experience with GM Mode. I usually play it hardcore. Now? I can't even consider playing it...
Not to be a dick, but it appears as though most of your frustrations are coming from the fact that you've screwed up as a manager, rather than anything that EA has done for you.
1st - If you are not getting any offers, adjust your trade block.
2nd - If the CPU keeps sending you the same trade, adjust your trade block. Chances are there's something on your block encouraging them to send that trade.
3rd - The CPU has been offering ludicrous trades since 2010 or whatever year the game mode was implemented into the series. You aren't over it by now..?
4th - Draft picks are moved several times over the course of the regular season trades. To say they only move on draft day is ludicrous. Is it a deep draft coming up? Why not try and stock up on late round picks. Is it a shallow draft? Why not start throwing later round picks into deals to add as kickers?
5th - I KIND OF SMILED at your issue with Rundblad getting claimed. FINALLY YOU and others can comprehensively understand that 2-way vs 1-way contracts have nothing to do with waiver eligibility; that means was entered into NHL 12 as a simplified way of handing waivers and movement between rosters, but the truth is that it's wrong. 2-way contracts have NOTHING to do with waivers. That's why there's a seperate heading/column that says.... wait for it.... waivers..... should have looked there to see if your player was eligible before moving him. But hey, we all forget sometimes, no problem...
5th - ...but, every time you move someone between rosters who needs to claim waivers, the game sends you a WARNING THAT THE PLAYER MIGHT BE CLAIMED. Missing two obvious cues on the same player? Not EA's fault mate, that's on you.
6th - On the issue of contracts; I can partially see your frustration. But to be honest I have no problems with how they've setup their contract structure. At the end of the day, it's a game, not a simulator. I want a game, which is simple to play, and many aspects of Be a GM have gone for a simple approach rather than an overly complicated one, which is preferred. If you manage your cap tightly, it's not hard at all to make trades and get things done. Even under this revamped trading system.
7th -
If you are at the maximum cap for your team, and the game is warning you that you are at the cap ceiling and that you need to make a move....MAKE A ****ING MOVE! Or let the CPU make the move for you - just don't moan when the CPU moves someone with $ down to your minor team. Chances are, moving the ELCs between rosters probably wouldn't have been enough for you to get under the cap, and as a result, needed to move more money. Yet again, that's not on EA, but on you - poor cap management. If you had a bunch of waiver-eligible players capable of being moved down to your farm team at no penalty in order to accommodate the trade you just made, why not just go ahead and do it?
8th - There are problems with Be a GM. No doubt. But there's no reason for them to remove it. There are countless numbers of people who enjoy the game mode, as evidenced by the numerous yearly threads here dedicated to the game mode. If it's not for you, that's fine - it's a challenging game mode that clearly not everyone can master without a bit of savvy and understanding of how it works. That's OK though, NHL 13 is a deep and invested game, and I'm sure there's another game type that you can find. There's no reason for you to sit here however, and start blaming EA for the fact that you simply aren't good at the game mode...
