Thinking of coming back to the game, and have a few questions?

[Nerael]

First let me say: Welcome back

well, my first question is why is the client download speed throttled between .3-.6 MB/s when I get 1-2MB/s on most other games? (my cellphone gets 14MB/s, but that's an entirely different story) I can get over this, because the actual game is what I am wanting to play XD but at this rate I won't be able to play for another 5 hours.

I think this is an issue with either firewall or piracy detection software. Last update I downloaded with 5 MB/s so I'm pretty sure it's something on your side.

Secondly I have a 36 Whitemage and I remember not liking to quest with that character, because the 2second GCD made solo combat tedious and boring also

All casters have the 2 second GCD. However if you want to run as a healer you don't really have a choice. Questing is indeed more tedious as a healer. However I've found that in fates and any other group content you are a VERY welcome addition (50 WHM here). Perhaps SCH is a bit better in this regard, but I have no experience with that so perhaps someone else can fill that in. Especially with the SCH pet I can imagine things are a little easier than solo WHM with questing. I can tell you that at a certain point practically nothing can kill you as WHM on the normal map. (SCH has a lot more micromanaging

If you like fast paced and are thinking of switching jobs I'd recommend BRD\LNC\PUG. They are quite fast and don't suffer as much from the long GCD

besides the character is a girl and I want to play a boy, should I just make a new character? I already used the free recustomization and while I can
probably pay for a new one I don't know where to do that if that is even possible. I haven't even tried any other classes at all lol.

Personally I wouldn't waste the money, I'd simply create a new character. Level 36 is not that high and quite easy to reach with some classes. It'll also give you a feel for the game again

Finally is there anything I need to know about the new content?

Quite a lot to be honest. I kinda suggest you take it one step at a time though. Most of it is self-evident
