disagree, 40 is where newbies get nomed by players who are scared of 90 arena, and soft cap 40. 90 players tend to use 70 with their alts when their bored, 40 is usually players who can't cut it at high levels, so they max out a 40 to nom newbs xd. Most 90 mains don't +18 a 40, they can enter with a +5 and troll or at least do reasonably well.
edit: even if a few 90 mains have made a few troll 40s they almost never use them. Trolling without any competition has a very short shelf life in terms of being interesting.
edit: just realized this was quil LOL so idk how it works there was thinking ponchee...lol. But if i remember correctly most arent close to 90 on quil.
