New to prot warrior, tanking 16+ keys, need help with reviewing logs.

[scarlet hound]

I'm new to prot warrior and tanking keys at a semi-competitive level and I'm starting to feel the punishments of playing incorrectly/poorly in keys. I am a DPS main(not warrior), but tank keys and i have no idea what i'm looking for in logs. Wondering if someone can help me figure out what areas I need to improve the most on going forward into higher keys.

Few things stick out:

You're wasting 8-10% of your rage, largely through not using ignore pain when you need to burn rage. If you look at 2:30-2:50 in your floodgaste you are fighting a pack and just sitting at 100 rage for 20 seconds.

You sent 33 violent outburst procs on thunderclap, instead of blast or shield slam. This is an egregious damage loss, probably your biggest issue. https://www.warcraftlogs.com/reports/Ct4K1VcXYQfrp2HZ?fight=71&type=damage-done&source=2&sourcebuffs=386478

Your blocked hit incidence is 84% which is ok, but you should really strive to get it to 90ish, you're getting hit in the back a lot while gathering, and this is primarily where you take damage

your overall shield block uptime at 82% is also low, that should be closer to 93 at your haste level.

you're playing fight through the flames instead of armor spec - not really a good play at this key level

you arent playing shield spec and instead playing enduring alacrity - dont do that either, losing a lot of tankiness for not much dps gain. yes I know kira/yoda/<insert streamer here> does it, you aren't them

at this key level I would consider dropping battle scarred vet for massacre

youll gain a reasonable amount of boss dps

finally - generally speaking your boss dps is low, a lot lower than I would expect at your gear level. This looks like youre just not prioritizing shield slam and blast to get into a feedback loop enough - for single target shield slam should be basically on cooldown with the exception of when you have two blast procs, spend one and keep shield slamming

make sure youre tracking your burst of power procs and using them
