New player - questions about endgame and other stuff :)

Hey Lucy and welcome to FFXIV!

I know of the dps/heal meta in this game and I dont mind it but between WHM and SCH, I assume WHM usually gets to "main" heal? Do you spend 90% of the time dpsing on the second healer? 50%? Do both healers spend an equal amount of time healing and dpsing? I know different groups may do things differently but what's the usual way people prefer doing this?

Currently the optimal way to do this is having both healers DPS during appropriate windows. It depends a lot on the fight and the healers. For example, in our group with an AST and SCH (me), for the first A9S miniboss the AST solo heals while I never leave Cleric Stance, but on our first A11S win the AST actually had a bit higher DPS than me because I spent so much time (over)shielding people in the fight. The current optimal setup for raids is AST+SCH, WHM isn't as sought after.

What consumables are you expected to bring to raids/parties? I've seen food and stat pots so far, is there more? Are you expected to bring the "best" consumables or are people usually fine with weaker versions?

For static groups, people are generally expected to bring food an potions. Both should be HQ, but they don't have to be the absolutely best available. Our group uses Draconian pots and Priestly Omelettes because they're cheap and enough for us at this point. As a healer, you may want to use MP pots for progression (for emergency situations) and then MND pots for clears and farms (for DPS push phases).

I heard/read you dont really need to push your dps to the extreme to clear content. Does that mean you dont usually wipe to enrage/too low dps? Are mechanics usually the main problem?

In current raid tier, there are two easier raids (A9S and A10S) before you'll encounter one where it's even possible to see an enrage with a relatively good group (A11S). The issue with that one is keeping up good DPS while doing mechanics (and of course staying alive).

Is there a list of popular/recommended linkshells somewhere?

Don't know much about linkshells, sorry!
