You can't invent new wheels. The MMO genre has already tapped out how many unique roles actually can fit into games before players start stepping on each others' toes. If you design marauder to be a better tank, gladiator becomes pointless. If you make gladiator a better damager, marauder becomes pointless. You can not solve that problem, so you shouldn't even try. This problem has been in this genre for 15 years. It's permanent. Marauder will not work as a tank. Gladiator will not work as a DD. Otherwise, they render the other job useless.
Lancer is the only meleer who has a shot at being great. It can be the new corsair. The damaging party enhancer that CANNOT be made up for by simply kicking them and adding an archer.
Hate controller was a viable role in FFXI, but it was POORLY designed. If they want to make pugilist a hate controller, that'd be worth a 2nd try, but even that is dangerous. Make hate controlling annoying to people, and they will HATE the job that does it and invent ways to not need it on purpose. That's what happened to thief.
Each job MUST be more useful to a party than kicking them and adding an archer. In reality. Not "I can crowd control" no, you don't crowd control. Not "I can tank" no, you don't tank.
People do not understand the concept that any advantage your job MAY have is not an advantage if it is NOT DOING IT, so if you are in any way paying for that advantage that you aren't doing by being less good at what you are doing at the moment...you're a gimp. Marauder is that gimp. It pays for being able to tank even when it's not tanking, by having lower DD output than it should, which it is currently and usually always is doing.
A marauder can claim it can tank all it wants. Gladiators will do that job, so no one cares. Marauders can claim they can AoE, but mages will do that job, so no one cares. Marauders can claim they can DD, but archers will do that job, so no one cares.
Same reason that a job's weakness is not a weakness if it DOESN'T HAPPEN. Archers aren't defensively weak. Parties are set up so that they don't take any damage. Dead enemies stop attacking.
Marauder can't win as this pseudotank pseudo DD. It's bad at both so....just whatever the marauder THINKS he's doing just get the person better than he is at whatever that is. If damage, archer. If tank, Gladiator. If AOE, mage.
As expected when you concentrate peolple who think theyr'e "experts," on the internet, the marauder's board has more cluelessness about the job than the general discussion board does. It's unfortunate that this topic was moved.
