If you hate it that much, you have 2 options:
1- Delete it without thinking about it too much and push one of your other alts.
2- Make it a Lopang silver source and see if Berserker will get any QoL/Buff with the new balance patch from KR, then decide if you still hate it or not. If you still hate it, follow the first option.
Lopang + Chaos
Use the Stronghold Ships to do your guardian(s) if you really hate him that much.
Pointless to delete any character if you can afford to buy a slot and move him to page 2-3.
I would wait until the next balance patch because there is a very very small chance that it gets a revamp. I fully get it tho I really want to delete my sorc.
If you can’t play it then don’t. Simple as that. Yes, deleting 1500 char is not a good idea from gold-efficiency standpoint, but you shouldn’t force yourself to play characters you don’t enjoy. If you have spare character slots you could keep it as dispatch alt. Will still bring you some mats, gems, gold AND you will keep the character if you ever feel like playing it/some balance patch comes.
u went from 1 bad class to another
delete both 
Dont delete it.
Do rested chaos with it because its giving you new mats.
Never delete a 1500 character, downgrade to lopang/rested chaos dung alt
You know what it takes and cost to get a character to 1500+ and you want to delete it. NO COMMENT.
i havent deleted that high but i’ve deleted a lot of t3 chars. For example i didnt want to play black blob, even as an lopang slave so i deleted her with all her mats.
At the end of the day it doenst matter as long as you enjoy the game you will get 6 characters to brel.
If you feel like you want him deleted, then just delete him. It’s just a game and you don’t really loose anything. It obviously bothers you, so just do what you want to do.
Found the issue. Playing BT spec instead of Mayhem. BT is so boring compared to playing Mayhem. Did you go for BT because it was cheaper? And no way it’s worth deleting such a high ilvl character while also being very geared.
Sir, play to have fun!
This is not a work 
For a time of about a month or so I also hated to play my GS and switched main to Glaivier. Now since Brel release I enjoy GS again.
So just do rested and when you want to do something on it. But never delete it.
Not at all,
I think you can delete all your chars and it won’t really matter.
I hope this answers your question.
There’s no need to delete the char unless you need the character slot, even then you can always get it restored by a GM
Do chaos and guardian and sell the mats or use the mats to push a new char.
If you don’t enjoy it anymore i’d say go ahead and delete it, i’ve deleted a 1430 bard, a 1400 striker and a 1415 deadeye, and If i recall correctly a 1415 arcana.
Granted they’re not as high as your 1500, but It made me room to try other characters i wanted to and currently enjoy more.
exactly what i was about to say , now if its EW deadeye, and he plays like a god, then its worth it, if not
it totally okay to delete, ive deleted some (wasnt that high, but still fuck it, its all good)
like a lot said before, i’d actually keep as lopang and chaos alt (whenever i’m up to, not daily) and only delete if you’re needing the slot. for instance, i got 12 chars, and i only deleted the ones i hated, and would be chaos and lopang only, whenever the class i wanted to play launched.
lmao if you have a lot of money just do what you want
