How would group of 4 DPS and 1 healer clear HoL (or pick any dungeon tbh), if they have no plate/melee to "take the aggro" aka tank. Who gets the blame? Healer. Who gets the kick? Healer. Who thinks they are the main characters, and everybody should accommodate them? DPS's.
No, there are way too many random factors that makes the 4 DPS 1 Healer RDF's too random to have RDF's completed reliably.
- Gear (RDF has min. ilvl, but it doesn't take a 2.8k healer having to heal 2.9k Mages who have the aggro on 5 mobs at a time into consideration)
- Skill (DPS&Healer, and ability to talk and coordinate)
- Group composition
This suggestion only works when:
- Premade
- Leveling (probably 15-60, on average)
Did you stop to thing about all the underachievers that would ignore all the "players should understand that queuing into a group with 4 DPS requires a knowledgeable and experienced healer to fill that role"? Btw, it also requires brained DPS (challenge impossible), so let's not put all the stress on the healers?
There's no room for player choice if it's random.
