I've read that this build https://gwpvx.fandom.com/wiki/…_7_Hero_BiP_Melee_Support
used to be the meta for PvE hero teams a while ago. Now there are these two builds:
Why was the necro build retired? Mercenaries were already around when it was created, so I presume the use of a necro instead of a fourth Mesmer was intentional. Does the fact that it was replaced mean that four Mesmers are superior, meaning the second build linked above is also better than the third? Or am I misinterpreting things?
Which is currently the overall best build/the meta for hard mode PvE?
