The bonus XP event in WoW is unusual in a way that you’re constantly getting drops of satchels with gear, but it’s a nice bonus. I didn’t really jot down the numbers of how much increase percentagewise it is (with the XP potions), but it’s fast enough.
After 2 nights (and doing other things), I got my 4 toons to 72, 75, 76, 77 – all from 70 (but not necessarily 0% there).
You do get a basically guaranteed epic level-appropriate weapon and a BoA 30 slot bag in your first satchel, so probably worth taking out even those alts I hadn’t planned on playing for a single quest or until the thing drops. And of those characters I have another 10 or so. Oh well.
That invasion event in Hallowfall though? I hardly read about and people told me it was bugged or not exciting and not useful for our mains, but apparently you can get some 630ish gear for alts. Will look at this later, guess I’ll focus on leveling.
