As someone who just went through this hell, NO, please do NOT remove it. Attunement is a natural selection of bads and slackers, who don't deserve to have anything better than ****ty t4. Especially on a server, where you can buy really damn good epic gear. I don't want to see these people, who don't know ****, who never even read tactics for one boss, to get into t5 and gods forbid, to even get boosted and get some loot. I'll be severely disappointed in this server, if they remove t5 attunements.
