That post basically died off. EA and PopCap haven’t touched balance in GW2 for years now — the last meaningful updates were way back, before Battle for Neighborville came out. At this point, the devs have completely moved on and GW2 is in maintenance mode, so any talk about rebalancing on the official forums just fizzled out. If you’re hoping for changes, the sad truth is GW2 is frozen where it is, and the only “updates” it gets are server-side fixes to keep it running.
