Theatre of Blood is an end-game raid that was not intended to be solo-able at all, let alone in mid to late game gear.
You could argue that there are players on OSRS that have soloed TOB using Guthan's but they are among the best mechanical players in the game and are utilizing mechanics that aren't coded on Alora.
If you want to solo TOB it seems the logical solution is to do the content needed to get end-game gear. COX, TOA and Gauntlet are solo-able content. Nex can be doloed or done in small teams.
Makings things easier isn't the solution to not wanting to spend the time to get the items needed to complete solo TOB.
I'm actually a player that brings guthans for these solos. Every aspect of the theatre is completely possible with more time and skill apart from ONLY this dps check, which wasn't even included before. The two weapons that could consistently get past this are scythe (which you get from the theatre) and the rarest COX item. You can solo both TOA (yes, even the highest invocations) and COX without end game gear, which you could argue are also end game raids? It's not a lazy issue either it took me 1hour 20 min with a staff to do a solo (mostly due to slow nylos as well as this dps check), which is almost 3 normal trios of time.
If I didn't have 1 of the 3 highest end game items I'd just be locked out from even attempting, though I'd have the skill to complete it. The only reason I bring the staff is for the dps check there's no enhanced mechanic or whatever that I could perform to get past that aspect.
You state that it is possible in OSRS for the best mechanical players. However, I'm getting the impression that, for some reason, you don't want the same to apply for the best mechanical players on Alora
