I feel for you. The Timeless Terrace map is essentially all the bad griefing events in pvp form. Some people enjoy it a ton, most people do not.
In all honesty for this patch, the Xeross weapon and Armor are the biggest allure to me. Yes, they are missing crit on the pieces except for the weapon, BUT they all have max tuned HP/Acc/MDef/Pdef, in addition to having identical base stats as Bitterthorn, which are all vital stats for pvp because what use is max crit if you have no defense? Attack is better for pvp anyways.
Here's the big catch: Our 7.7 patch is missing all the quality of life improvements from the 7.7 update patches, especially the one that makes the hundreds upon hundreds of Heart of Protections needed to craft a full set more available. I can't find the patch which they were fixed but I know for a fact they made the more available from bosses rather than killing 2k bosses to craft a set.
We actually missed most of the quality of life patches that came after. Our update seems to stop before the June 24th 7.7 fixes.
