I guess we can’t respond to topics in the community council area? I agree the system needs a rework, but they highlighted the cost flaw of the system. Many people have already dumped gold, or other currencies (Darkmoon, Timewarped, etc) The easy revamp would be to make the items scale to the previous expansions ilvl and if they are level 6/6 they should scale ahead that much. Giving you a nice advantage and not nullifying someone’s time, unless you just refund them the cost….
And why not just add a bonus +5 % XP gain back one piece for each heirloom worn and the final set bonus is your rest doesn’t deteriorate? That or make it have 0 durability - Indestructible (it might already have that not sure) Leveling is fast anyway, and with heirloom gear the goal is to keep it on as long as you can. You could leave everything as is and do the same idea with a +5% stat buff for each heirloom piece, then people might consider spending the gold sink or farm.
If that were to implement now you’d see a level one with ilvl 6 heirloom gear if the gear is fully leveled. And once you hit the previous expansions cap I don’t see why the gear couldn’t stay relevant for a level or 2. Just my thoughts.
