New PVP type

Alright, I was thinking of a new PVP type game and alot of my ideas are based off of the DotA custom map for warcraft3. Basically there is a huge map divided in 3 lanes. It is a war type (fits in with "guild wars" doesnt it?) siege map. Each party of 8 would get their own lane versus another party of 8. (maybe the parties can cross over somehow?) So its a grand total of 24 vs 24 or whatever the size of the parties should be. You would have to make a new PVP character each time you want to start a new game. Each player starts at level one and there are towers scattered along so as you push foreward, you need to destroy them along with creep spawns (a lil army I guess) that walk from town.They would spawn at regular intervals. The experience would have to be changed to be greatly increased to be able reach lvl 20 by the end of the game. Each time you level up, you can choose one skill to unlock for the duration of the game. Elite skills would be purchased with the gold dropped from monsters and that sort of stuff. The game ends when the teams reach the town (guild hall type thing?) and destroy the town main building (King?). Anyways, its really fun if you have played Defence of the Ancients before. Sorry for not expressing my ideas clearly but I tried :\

Enough said there...Too much trouble, this would never happen.
Leveling from 1-20 even if rapidly, is too long for me. Maybe a 4v4 team pvp with (2 lanes) as you said. 2 groups in one lane fighting, 2 in the other. Winners of each go onto Winning lane, losers (give them another round i guess) to losers lane, or leave game.

Base it off Tides of Blood instead...

I'm sorry, but I can't stand DOTA (TOB sumpremacy!!)

While I like the basic concept, this isn't really "Guild Wars material"
