I doubt that there will be a trainer as my request for a trainer got deleted off the message boards.
You've kind of requested multiplayer-only options in other trainer threads previously, so you might not have worded your request quite delicately enough. Or not posted it in the appropriate thread, I didn't see the post in question. But there's currently three requests in the thread, including mine that explains a bit on why the trainer wouldn't effect the online portion unless you were using the trainer during actual matches.
As for how the game is, it's basically a 2D MOBA with a whole lot of sillyness and a ton of fun.
