I was lucky enough to get a key for the Beta 2 from Fileplanet, dunno if it is a VIP one or not, but I got invited back for Beta 3!
Both times I played a Scout as I love Scout classes. Beta 2 only Guardian side was oopen, Beta 3 we had both Guardians and Defiant.
I played my Guardian to L 15 and my Defiant to L 19.
Defiant L 19, with Souls for Ranger, Marksman, Assassin. I have all the bow skills I want plus 2 good sword/knife attacks for when the mobs get close. I also get poisoned blades from the Assassin skills. I have a pet Razorback hog which is awesome and I pump skills into his and my health, I also have a Dire Wolf who is less awesome and got him at L 15, which is kinda unbalanced and I sent in a report about.
Pet window allows me to send in my pet to attack, call him back to drag one mob out of a group, and take it on with my bow at a place to suit me so I am not aggroed by the rest of the mobs. Razorback can keep the arggro on him I can also Transfer Hate to him for a set time if I get mobbed. Works OK usually, depends on the level of the mob.
I could also Heal my pet from the time I got my first pet, and i can do that while in combat which is very useful.
I can take on a level or 2 higher than me alone, so long as it is one mob at a time, so yes, I am very happy with my build.
I also have a racial extra kinda like a berserk thing for a short time as a Dark Elf (sorry can't remember Rift name for the species) that helps if my pet dies or I get mobbed.
Scout was a L 15 with souls for Bladedancer/Assassin. We only got 2 Souls in Beta 2, so she had those 2. She could use a rifle, blunderbuss I think it was, and did most damage with her blade weapons. I used the gun to pull mobs away to me and engage in melee. She was slower to be able to hold her own as she was still a Light Leather armored character like my Ranger. but at L 15 was beginning to have the skills to hold her own.
I know each skill said +1 to combo but i never did find out what the combos were, nor did I actually observe them. I liked that neither character had to worry about ammo, it was refreshing not having that expense or worry!
Of the 2, I preferred the Ranger with her pet more. :) I didn't need to Kite with her at all, I could stand my ground and just shoot at the target my pet was attacking.
