Agree - not a chance now. I don't stand a hope in any Tower fights any more. I had steadily worked my way up to League 1 over a number of weeks before the update. I have HP of 382k, but every fight I start in League 1, my opponent has a minimum of 2500k.
I'd have to keep playing and playing to get kicked down level after level after level without a single win until I'm back to where I was many weeks ago. That's not fun or motivating.
Definitely sad that the game has been ruined for me, but on the bright side, I've gained back a huge amount of time that I was spending playing. The update also good for my wallet - it has completely removed my appetite to spend money on the game.
