Something that somewhat unsettles me about healers that I've encountered on this game is that they take the time to DPS at all whenever a tank is taking any noticeable amount of damage.
Perhaps I'm from a different school of thought, but I'm a firm believer in pre-casting spells to prepare for oncoming damage when I know a large attack is coming. It is also true that any one in a tank role should be using their active mitigation skills to help this, but I still cannot find myself wanting to defend a WHM insists on spamming Holy in the cleave zones (facing away or not, sometimes they get clipped) and refusing to cast anything other than the occasional Medica.
For OP's particular situation, I think you'll be encountering a fair amount of people that generally assume that a dungeon doesn't mean 'hey, group activity! I may be responsible for things' and more of a 'I hope everyone here will carry me so I may collect my exp/loot/rewards and I'll be able to do as little as possible!'. Often, if you are not in the company of friends, expect to do twice the work you normally do and mental preparation is required for this.
I consider myself a career tank in MMOs. I've done it in many, many forms and find it to be my most comfortable spot. Most of the time I make the extra effort for myself to have the right gear, know the fights before hand and keep as many tools available to myself as possible as a 'just in case' measure. I played healers in all of these titles to further understand what I was subjecting people to when I did tank and discovered quite quickly that very few people care about others in PUGs. In this game, it hasn't nearly been as bad as I've seen (Save for a few CT runs and a WoD here or there). So I consider myself quite fortunate.
tl;dr
If you aren't running with friends,expect the worst and do whatever you can to prepare yourself for it.
