Some games I play are pretty well matched and become quite challenging and fun... however, one thing I have noticed is when creeps start attacking your citadel, by the time you kill them off, the next wave is there, and so on. It makes getting back out of your base very tough if you are not playing a character with any AoE abilities, or if your AoE abilities do not cover a huge area or do enough damage to kill off the creeps.
Well anyways, one game I had was really really close, but everytime we killed off a wave of creeps, another one was right there again. We ended up losing, even tho we had a lot of money, and were upgrading, and killing off the other teams Demigods, the constant creeps kept us stuck and also kept racking up the Citadel damage.
This gave me an idea. How nice it would be if you could purchase a Citadel Nuke! Something for like $10,000, that would blast the area around your citadel, killing all creeps instantly. I tell ya, if we woulda had one of those that last game, just to get rid of the creeps that kept building up, we probably would have easily won.
