Agree that the random element introduced with engineers is ridiculous... but to me, more egregiously, is how it completely unbalanced pvp with no hope of it being "re-balanced" (some may argue it wasn't balanced previous to engineers!). Simply put, engineers was a "content addition" done with little consideration for game balance but as a benefit to the devs, would cost very little (development wise) to do. There's very little actual content to it at all, and engineering boils down to long range fetch quests with crummy rng as the reward.
Completely agree there, mate! Engineers created a near insurmountable grindwall barring all but the most dedicated from entering into pvp with Open Viable builds.
