mrrrrmmm...definitely not *standard* practice for me, since you ask - I do respec occasionally, but mostly I do it for a few specific reasons.

1 - checking out some builds, someone has recommended a skill or morph that I had written off as useless because the text description made it sound pretty lame, but turns out people have found a way to synergize it with other skills and rotations to make it far more powerful than it sounded in the text description

2 - total re-evaluation of my base character - had a stamina templar for the longest time, just didn't find him satisfying, so totally respecced him into a magica templar instead - enjoying him more now even if he is vastly less effective

3 - cp respeccing - this I do fairly frequently, because they confuse me, so every now and then I do some more research online, learn/understand them just a little bit better, and realize that I could spend my cp's far more synergistically than I did the first (second, third, etc) time around

4 - this happens rarely, but sometimes I'll respec morphs when there's a major skill change from a patch or whatnot, and a particular morph is either considerably better now than it was before, or considerably worse - respeccing morphs is nice and cheap so I don't mind so much

those are the top 4 reasons I respec - I have only 1 dedicated crafter, so respeccing for adventuring then back into crafting has never been a thing for me, plus, quite frankly, you don't need to respec a crafting character - the basic run of skills is usually sufficient for all overland pve content, which is how I lvl up - hell, on my crafting character, I don't even try to min/max gear - he just gets sorta the most useful selection of trash my other adventuring characters pick up during their dungeon runs and whatnot

First question do you have an lack of skill points or want to spend them on stuff like crafting, if you it might be an idea.

On the other hand resto staff open up the option to do group dungeons as healer, this is relevant for the upcoming event and each dungeon quest unlock an skill point.
Just go in on normal pledge and heal and do damage then healing is not needed.

You can always respec later.
I rarely respec but has an project of making an Bosmer magblade to a stamblade and will probably make my Khajiit stamblade magblade down the line so leveled light armor, destro and resto staff on her.
