I love td games and lame t the severe lack of quantity of more than puny budget ones, soo yeah. However i dont really consider dota style games to be very TD-like. They are more group pvp-esque imo. Even if you are a full time lane pusher its not very td like since mazing and/or tower placement are simply no factors at all. Furthermore pvp is still extremely important for lane pushers since they can cost their team the game simply by failing to be cautious enough around enemy gankers.
Anyway i dont care for dota or lol much but ill give this a try, but am not hyped.
