1) there are 2 skill spheres. One for left click and one for right click. You can place anything on the skill tree there including your basic skills which are attack left hand, attack right hand, and attack with both weapons. If youre using a two handed weapon such as a rifle, just map attack left or right hand on your left click so you can open up a skill to put in your right click. (drag and drop)

Now if you have dual pistols or swords you can map attack left to left click and attack right to right click so you can have maximum control, or, as i usually do, map attack with both weapons to left click which opens up a skill to be put on your right click. You should always use a skill on your right click. A cool thing is that there are three different weapon switches you can use with F1, F2, and F3 and you can map a different skill for each weapon.

Also, some skills can be activated with shift. And example is sprint. When youre moving forward youll see on the bottom left the sprint skill light up meaning all you gotta do is hit sprint to activate it. Very useful as it doesnt take up any slots that can be used for more important skills. But if you also activate tactical stance from the marksman or hunter skills onto your shift key (do this by clickin the up arrow next to the skill till its blue), now you can enter tactical stance but hitting shift while standing still, effectively opening up another skill slot for something else. Even more, if you map escape as a shift skill, if youre backpedaling away from an enemy, youll see the escape skill light up meaning you just hit shift to activate it for a getaway. So by using the shift functionality youve effectively saved youreself 3 skill slots that can be used for other skills.

2) Yes most definately. There are 3 factions - hunter, cabalist, and templar. Now each faction has 2 sub classes. blademaster & guardian for templar. evoker & summoner for cabalist, and marksman & engineer for hunters. So basically there are 6 classes with a different skill tree for each of them. there are some skills that overlap, such as tactical stance for both marksman and engineer, but for the most part each one is very different.

3)Well, not too many with youre basic attack but different skills offer up different attack variations and animations

4)Pets are really only in two classes - the Engineer and Summoner. I love pets so ill be trying them both.

If you have any other questions dude you can always pm me or ill be on TS a lot this week since im off on vacation. I cant wait till tues midnight. We definately gotta hook up man.
