New Citadel Upgrade: Increase Tower Range. Add it. Add it now.
Because no Demigod should outrange towers on auto-attack, don't give lame excuses. I don't care that Rook can destroy a tower faster than a Regulus can. The fact is that most Rook deaths occur when he comes to attack a tower by himself, by a teleporting or ganking enemy. Regulus can do it from away and he's safe, so as soon as someone teleports in, he can run away, and unless you're Erebus you likely won't able to catch him, especially since most regs take boots, wand, or anklet to kite. Regulus isn't giving anything up since he can get kills and assists standing right where he is, and all takes is a couple of mines to decimate a group of creeps, and since the creeps run near the towers often he can damage both the creeps and tower getting xp and making the destroying process faster. You can't always be there to chase him away.
Lame enough on Cataract, it's extremely lame on Zikurat where the towers by the 2 inner flags are close, he can demolish your tower while in safety of his own, while other DG can't even get close. Once the tower is down, that allows his team to push the lane, which can often be an enormous pain to push them back, especially since the paths are so narrow and mines recharge way too fast.
