Does the current combat rotation make this experience feel like you are playing a Commando? Why or why not?
Speaking only first the first few levels (as I've got meetings in a few minutes), it doesn't feel all that different from the current Commando on the live servers.
As you’re beginning from level 1, do you feel you have enough abilities that keep gameplay interesting?
I only got to level 4, but I did check the trainer to see when abilities would be unlocked. It looks like Commandos will be limited to Hammer Shot, Explosive Round, and Charged Bolts at level 4 and will gain Supercharge at level 10. After that, the next new ability will be High Impact Bolt at level 15. One of the defining Commando abilities, Full Auto, isn't available until level 27 on the PTS. I personally think Full Auto should be available much earlier to give some variety to the abilities. Two of the 3 offensive abilities are instant-cast, Hammer Shot and Explosive Round, and one is a 1.5-second cast, Charged Bolts. Having Full Auto available before level 10 would add a channeled ability as well without overwhelming the player with abilities.
Are you able to defeat enemies at a reasonable rate?
Yes, the early game is far too easy. I was never in any danger of dying no matter how many enemies I pulled.
Do all your abilities feel like they’re working together?
There were only 2-3 of them, so yes.
