I wouldn't say a complete overhaul is needed, but I do think the game could use a breath of fresh air. I'd personally love to see forward progression in the game slowed for a while so that development time and resources could be spent on addressing the long term health of the game.
While the 4 month constant update schedule always means there's something right around the corner to look forward to, it also means the developers are locked into a rigourous, tightly scheduled development march that doesn't leave enough room for being really creative or for addressing some of the underlying issues that the game has faced for years now. The best we get is band-aid fixes that they can slot into the regular development schedule as time and staff are available, and only in things surface level enough to be created while the game is seeing completely active development. Frankly, with the end of the current story arc this would have been the perfect time to do it. Put out fun little side stories and combat instances but essentially go into at least partial rebuild mode with much of the rest. It may not seem like much now but 10+ years on, the cracks that exist now are going to be massive fissures.
