1. Highlander is not 6v6 so folks should not attempt to apply the same logic they use in designing 6s rules to highlander. In 6s only 4-5 classes are utilized most of the time (2 soldiers, 2 scouts, 1 demo, 1 medic, maybe a pyro or engineer or sniper for a few seconds on lasts, rinse, repeat). As such by definition of highlander all classes need to be viable. Wrangler is a powerful addition to the engineer that makes the class quite useful in comparison to when it was not in the game.
2. Top teams in highlander have ZERO problems taking down a wrangled gun. If you do, you need to try a new strategy.
3. Wrangled guns INCREASE the need for teamwork from the opposing team because in order to take them down quickly you need to coordinate attacks from multiple classes. If you think a wrangled gun is OP try coordinating a DH soldier, demo spam, AND a spy sap. Shit melts like butter.
4. It's been debated about 4 times already and most of the league wants it in and it's not going anywhere.

And furthermore, it is my opinion (not UGC's) that the result of the HUGE number of bans and class restrictions in CEVO/ESEA have hampered growth of 6v6 over the years. 6v6 is quite small in comparison to highlander and pub TF2 in general. I feel this is because it is DRASTICALLY different than stock TF2. It's incredibly difficult to get public players interested in 6s because 1) they probably can't play the class they love and 2) they definitely can't use majority of the weapons they like. Maybe that's one of the reasons ESEA has 68 teams this season instead of the 117 it had last season. People might be getting bored playing the same game they bought in 2007.
Now, I can't wait to read mustard's epic paragraphs dissecting my points and the instant 4+ frags I get from my fan club.
