I could definitely manage all 3 roles with a single alternate item in TSW (8 total: head hp/dps, major hp/heal/dps, minor dps/dps/dps) if it had cost 6 months per item to add more to my inventory instead of ~a week. Addition of anima allocation and it’d be trivial to do every role in dps gear. 3 year mark in SWL and I only have 5 talis maxed out. I’ve been subbed the whole time, although for the last 6 months I haven’t bothered opening loot crates cause there’s nothing new.
Unless they go full on changing the amount of damage mobs deal type rebalancing, I don’t see how they can make tank glyphs useful. They don’t prevent spikes as they did in TSW, cause there’s no boss dealing little enough damage for ‘spike’ to mean anything.
If they are rebalancing the actual damage dynamic, I hope they fix the other longstanding problem with group content, that it’s set up to where you can win if you make no mistakes, and if you make any mistake (well, as tank/healer) you restart the 10 minute long encounter. It’s never been a good type of difficulty to make it take a very long time for anyone to win.
