<font color="gold">I voted for "It should be changed". I'm not much of a fan of DBZ, in fact, I dislike it, but I enjoy this mod.
I also think that melee should be included. However I think it needs to be balanced. Currently melee is overly effective (note that I did not say overpowered, because if I did, surely someone would say "but it only does x amount of damage". Sure, it does take skill, but just because something takes skill, does not automatically mean it's balanced (Take CS's AWP for instance).
The swoop, is the fastest means of movement in the game. So evading it with anything but the swoop is unlikely. Which is probably where all the complaints about melee lie, it's just too hard to evade it with anything but the swoop. Flying and turbo are significantly slower than it. And of course most techniques require you to slow down and charge it for a few seconds. Some even require you to be still. The effect of melee (being thrown off and propelled far into the air), should probably remain. I propose that the speed of the swoop be decreased.
The truth is, many servers turn into meleefests.
