It’s my, probably, second topic in the forum, I play Blizz games since I was a baby and now I’m old and a digital monkey. Brief introduction then I go to the point.
8 years in Hots and counting, I paid a lot and I don’t regret it, I keep playing because this is THE game. Yes.
This game is the fusion of all Blizz universes, and it’s the least in your list, too bad.
Why?:
It’s free and it’s a good chance for new players to experience Wow, Starcraft etc…then they probably will buy one of those at some stage… but no, let’s spend money in useless marketing stuff or streamers etc…alright, not my business.
You could easily reroute the 1% of the money made in Diablo Immortal to Hots and it could be still alive…alright, not my business, didn’t get a degree in economy or stuff.
SAID SO, back to the subject of the topic:
Could you PLEASE and AT LEAST, make the boxes not seasonal anymore? like… It’s been 2 years of Christmas loots…seriously…is it that complicated to code something like " you win a box and decide from which season?"…oh no, let’s give to these LOVELY players a NICE copy pasted mount as a reward for loyalty… wtf 
Do not cut or delete this message or it will be something serious…
No hate here, just hello Blizzard, wake the f up.
You don’t need to worry I’ll keep buying all your games…but you know… where all this greed will lead you?
Peace and love
