lol what i mean by zerging is running through the dungeon while monsters aggro and attack, just to hit a portal and de-spawn the mobs. In other words, that is what the intentional strategy is for the first few maps of the dungeon, which is, needless to say, "linear"

I understand that dungeons weren't necessarily for ranking up anyways, since you cant get passed R50, but I believe that some dungeons should be as trivial as the Water Temple in Zelda. (I went there.)
