Again, players such as EasymodeX is missing the argument at hand.
No one denies the fact that you can complete 100% map exploration, play with friends, etc… as a Mesmer. If your character only had one leg and had to walk at 50% of normal walking speed you could still be useful in WvW.
But the fact that every class is allowed a passive, singular slotted skill for increased movement speed out of combat EXCEPT us is what concerns many people. Whether it be 10% or 20%, the other classes are given one that requires no weapon commitment.
