Throw awat the iLv system, implement a PvE Rank system.

This may be true, but I think one of the reasons people set the ilvl higher for fights like Titan HM is because with a higher ilvl requirement, there's a greater chance at getting players who are competent. It's not a guarantee by any means. It just helps your odds.

Which is quite explicitly conflating gear level and skill.
