I have this bug since 2 months on one of my engi, but not on the other one. Did multiples reports about it and I never had an answer. It is not a big deal, the mech is useless underwater. We can’t give alac, the dps is horrendous, I switch to scrapper every time. But seriously Anet, it’s been almost a year and we still don’t have any solution for the mech underwater. The ranger has one billion pet perfectly functioning and you can’t do the mech ?
