I've recently been towering, and with my little time towering I've noticed many issues that go along with it. First off, lets start with AP shall we?
Alignment Points
AP and towering clearly don't go together like peanut butter and bacon, but it could simply be resolved with a few additional add-ons. When a player with 100 AP enters the tower, they usually just sit there, sometimes mocking the guild whom owns the tower, and do absolutely nothing of any sort. I'm not saying that this is an issue, more like a frustrating occurrence. You can add a block that doesn't let players with 100 AP enter the Tower (sorta like the no-tag no enter thing or no-tag can't hit flag). Because, in all honesty, player with 100 AP have no reason to enter a tower anyways.
Potted Life
Now, lets touch on the potted life. The pots that contain health, located in swamp tower are of no use to towering players. Why you ask? Because players whom tower usually have very low AP, so, the pots sitting there can't be used for healing. I suggest you remake the AP code, where the negative health affect for low AP doesn't occur inside a tower, thus, players may use pots to heal, or meditate to gain health.
Warps
Lastly, I'd like to finish off with tower warps. This topic is commonly talked about within the towering community, and has been for awhile. Clearly, Sardon's and Snowtown's warps are highly unfair to attacking guilds (Snow: You warp inside the flag room, whereas the other guilds warp outside)(Sards: You warp in the flag room, whereas the other guilds warp in the room before entering the hall)(DW: You warp in the room before flag room, whereas the other guilds warp outside)(Swamp: You warp in the water near flag, whereas other guilds warp outside). Most warps are unfair, and make towering more difficult for opposing guilds to take over, result of guilds overcrowding and holding towers longer than normal.
All in all, Towering is fun, and something to do since there usually isn't much to do. But, with these few fixes, towering would be improved, and more enjoyable for everyone.
