I thought that all the raid levels had the same health which is all that matters in terms of reducing the boss health. If people consistently fail, then sure it'll grow slower. But I doubt people that fail ELT will continue doing it over and over again. Even a screw up doesn't slow it down much. If you leave it at 20% health, you still got 80% of the credit.

Also, people are overexaggerating the difficulty of the raid. It is hard the first time when you don't know what to expect. It is also harder than typical raids. That just means you cannot hit repeat and you cannot bring as many TMR units. It doesn't mean it is something a person will repeatedly fail, unless they screw up.

I started 3 months ago and can complete it with a shitty Hyoh without any TDH stuff and without any friend units.
