They will not nerf it, IMC said it themselves. They will balance it to hand everyone transcendence 10.
Q: Item transcendence comes up too early in the game, and the effect it has on overall balance seems a little excessive.
A: Originally, we introduced the transcendence system to give items a higher degree of importance in the game. We don’t want to devalue transcendence, since it would negatively affect players who already invested in it, so we are reviewing ways to increase the supply of transcendence items in order to reduce the gap
If by any chance IMC changed mind and completely removed it or tone down. The balance will shift again in favor of clerics and Wizard because the best skills are on that tree. They nerf clerics/Wizard skills people will cry, tone down transcendence people will cry, make archers/swordsman viable people will cry.
Power creeping already exist in rank 7 (Hello ET) even before trans were introduced. You could say IMC balanced the damage based on ET hence they introduced transcendence so un-meta people could clear and farm there too.
We removed/tone down transcendence now we are back clearing ET in hours, then unmeta people will farm barnacles so they could buy lolo equips from meta people.
