Oh, I see what you’re saying. That’s an opinion, and in the OP’s case, it’s really up to the OP what is “correct,” but I appreciate that you feel transferring would be more worthwhile than rerolling.
Personally, I know what my choice was:
Of course, that was prior to paid transfers, and when there was sufficient evidence of server populations, but also prior to BGs being released.
I suppose whenever I read about these “problems,” it reminds me of a situation I had when Legion first launched.
I really enjoyed playing Feral (dps) in Arenas, and Legion introduced Artifact Weapons, which would require a lot of effort to upgrade. It felt like if you wanted to really progress with a spec, you had to choose one, and so I joined a raiding guild as a Feral druid, and worked on my Feral gear/spec, etc.
Something else that Legion introduced was Mythic+ dungeons, and in early Legion, Feral dps was abysmal for M+. I had felt incredibly pigeon-holed into a main spec, Feral (as not only would you have to prioritize a main spec Artifact Weapon for your Artifact Power, but there were also Legendary items that were spec specific and had a chance to drop - of course I prioritized my main spec, which of course was horrible for Mythic+, which was quite an important part of the game.
Whenever I would raid the issue, the question of “Well, how is Balance?” would come up (Balance was quite good for M+ at the time).
It felt hopeless to me, and I ended up quitting. In hindsight, had I put some effort into building Balance (or Resto) as an offspec, I would likely have been able to maintain competitiveness, continued enjoying my druid, and not have had as hard of a time as I imagined. Once people had the gear to run higher M+, focusing down 1 target at a time became a thing, and Feral was desirable, and they also later made some changes to increase Feral AoE, which also helped for M+.
Anyway, good luck to the OP, and to anyone who finds themselves in a situation in WoW that they are not enjoying.
