Luvbunny, wrong. Just because you have freedom in ESO doesn't mean you dont have roles. Have you played ESO.
Edit: also this game is group play only about 15% of the time. Thats another reason you have people not knowing what "roles" to be playing or how to play them. Explain to me what role you are in your party made up of 1 person? And you are said person in a world that is not interactive with others unless you group up and do what, hunt 1 monster? You can't talk about roles when the game only put you in a group role very sparingly now, back to below:
When you make a group in ESO, the group leader decides who plays what role. They assign the roles on screen using icons and based on the playes in the group and their abilities and gear. So for example, If I had a mage, a templar, and a stealth/rogue in my party just by their class, It doesn't mean that automatically the mage is heal, templar is tank, and rogue dps. Because roles in ESO use more than FF's roles by predetermined class/job role design.
The mage might have full armor and put attributes into health and magic while utilizing skills with damage mitigation and aggro.
Templar stats went into stamina(dmg) and health, so they are using a duel weapon with high attack and skills utilizing tremendous damage output. Oh and the templar in this fight is using bow;
Rogue put stats into stamina and magic, is using stealth attack/defensive/support skills while using a resurrection staff as main weapon and daggers or sword as secondary.
So based on that, as a group leader, I would put Mage=Tank, Templar=DPS, and Rogue=healer/support. So see, roles aren't assigned based on just the class you pick, they are also assigned based on gear and skills/techniques.
Edit: Also, the abilites and skills you have are based not only on the class you chose, but also the weapons you use. So even though the above mage might have full armor, he still has access to his class mage abilities. But he wont have access to his staff magic abilities unless he equips a staff. Or he can just use a sword and shield and have access to those abilities while utilizing magic from his class. Also every skill when used enough can be ugraded once to include an extra function. You only get two choices for the upgrade and you have to choose the best upgrade based on "your" play style for your character. So basically I can have 3 of the same class in my group and they all can fulfill different roles depending on their gear and skill progression
Why people think tanks have to be big bulky people, mages have to be small or thin, etc. Why cant mages wear plate armor, why can't my tank heal, why can't dps cast spells and attack with a sword? And "special snowflake"? I pay for an open ended MMO to play and build my character how it fits my play style. It doesn't mean I can't be in a tank role. Why limit tank role to one set of skill or one class. I suggest you play ESO. I'm applauding ESO not for the game itself, more so how they approached making a game where everyone can find a place to fit without being subjected to "you are not good because you didn't use this skill when its your job" etc. If I'm a tank and I keep aggro on me and mitigate damage on myself and have a very good amount of health...and Im a mage wielding a staff or weiding a bow...how is that not playing my role? I created my character to fit the role I want to play, not the other way around, like FF.
