Yeah...it's sad to see that this is still an issue. I haven't received my crowns since August without having to submit a support ticket first. Had planned to cancel, but with Wrothgar coming out soon, I wanted to stay subbed so I could at least try it out and decide if I want to purchase. Plus, keeping ESO+ (even with having to contact support to get my Crowns) has given me enough Crowns to purchase it if I want.
I like the ESO+ bonuses for my alts, but I'm still deciding whether they're worth the $15/month. Since XB doesn't allow 3 and 6 months subs with discounted pricing (like on PC), it's really cheaper to just purchase the 3,000 and 5,500 Crown packs.
