I wish Gunbreaker would be a DPS class.

While I do think we need more tanks, I do wish it was a DPS job and the other planned job/jobs would be a tank instead.

And here we go.

A new tank and a new healer have been overdue. I have no complaints.

this SB added 2 dps jobs and 1 limited job which is classified for gear as a dps so tank and hlr jobs are by far long overdue they had to wait 4yrs for new toys time for dps to have a turn waiting that long me thinks

This right here I'm in agreement a new tank and healer is what we needed tbh.

I don't, I'm glad it's Tank.

I wouldn't have minded, but bear the following in mind:

Q: Why is Gunbreaker a tank and not a DPS?
A: There are two reasons. First off, if we added it as a DPS, the numbers wouldn't be balanced anymore. We already have a lot of melee DPS, so we didn't want to add any more. The second reason is because it was about time to implement the FF series jobs that people around the world had been requesting, such as BLU. We considered that a gunblade job would make a good draw because of its flashiness and appearance, and adding it as a tank would be great for role balance. We debated about whether we could make a tank different from the ones that fight at the forefront and in the end decided to go with gunblade. There were a surprising amount of people who predicted it'd be a tank - about 70% of the community. I think that means the players are also aware of FFXIV's job balance and design policy.
Q: Right now, the three tanks are well-balanced. What will happen when you throw another job into the mix? Can you tell us roughly what Gunbreaker's special characteristics will be?
A: Honestly, please wait until May for the answer. We'll show you how the four tanks will differentiate themselves, including their new actions. We've had three tanks up to Patch 4.5, and we see tank players' preferences with regards to MTing, OTing, tank stances, etc. I don't think it'd be good for the three tanks to form a "triangle", so maybe we'll balance them by having two MTs and two OTs, or make them capable of both. Right now, we're working towards a compromise as we adjust the actions. We'll announce the battle system details in May, so please wait until then.

So, I think the best attitude to take is to see what their overall plan for tanks is, and how GBR fits into it.

You could always just never be MT. :P

Sounds like someone didn't get to main what they wanted.

WELL Technically we never got Gunblader so you can still ask for Gunblader as a melee/ranged dps hybrid seeing as how Gunbreaker is just a broken Gunblader who can't use range.

Gunblader would make more sense as a tank FF lore-wise. In FF8 every gunblader seen has a protective role, protecting a sorceress.
In FF13-2, Lightning, who uses a gunblade, also has a protection role, but I'd say Lightning in general leans more towards the DPS role.
