Actually he is correct, those "5" seconds over the course of a long fight, there is only 2 atm really though, are pretty precious with just waiting on a AA and throwing weapon right away is around like what, 800-900 tp more ? That's huge in terms of DPS increase.
And if you need to be using Chameleon/Elusive Jump everytime is up, then you should probably look for a better tank most likely.
With Gae Bolg and what I consider pretty good gear for DRG with always coming on top on parsers, I rarely ever use Chameleon/Elusive unless A) Tank isn't that good, B) Tank missed Spirit's Within or something like that(which Curtana usually makes that not happen at all)
