Please remove it, it’s a terrible mechanic and a massive gimp in time for progression.
Either remove the requirement completely, make them far easier to collect (Seriously, you have to do a quest chain for each shrine and there is only 1 of them for each, and they’re spread the entire world apart), or significantly increase the buff time… 4 hours is a joke considering the majority of players are going to be nowhere even close to shrines for the entire levelling and gearing process. It should be more like a 48 hour buff, not a 4 hour one.
I haven’t actually seen a priest with the meditation buffs for months now. It’s a massively unneeded hoop to jump through, for something that everybody else gets without it.
