Oh what the character orb is being removed?? The horror, THE HORROR!!!
As someone who was originally introduced to MXL back before the orb was added (friend showed me the mod back in 2009-2010) I'm glad to see this being removed. I felt it made things too easy/a joke if you knew how to properly use (abuse) it and it just felt weird that you were stronger at lvl119 than you were at lvl120. Or at least stronger at lvl119 until you geared up and got the gear/charms/signets from doing lvl120 content. IMO leveling up should almost never make you weaker than you were before and definitely not to the level caused by the Character Orb. I understand minor tweaks to stuff like crit rates and what not to deal with stat inflation (this was why WoW went from +% to +rating as to allow for dealing with increased stats on higher level gear and to not let low-level gear potentially outshine higher level stuff, but I digress), but the stats you could potentially lose when you lose the orb was just so high.
Granted I suspect these are similar reasons to why you're removing it. But maybe others will be less salty about its removal with this explanation (not that you care about their salt).
