Pinnacle Towers - offer more attempts or lose players

I failed a copper tower and now it's closed. Are you ******* kidding me? This completely tanked my interest in trying to finish this content. This is an absolute braindead choice unless you want players to quit the game at this juncture. I'm not going to waste my time slogging around forever looking for another tower to fail.

Best choice: offer unlimited attempts at pinnacle towers. The bosses are already hard enough to make it a decent gate.

If that's too kind for GGG, then create a key for the towers that is dropped when clearing corruption nodes.
