In my honest assesment of combat roles, assault units should be self sufficient, able to cover most situations without the need of support, air, or heavy armor. Obviously with the exceptions to in which case you encounter unforseen circumstances such as encountering enemy air units. In which case air support is nice. Though my BIGGEST complaint about SL combat is you move slow, and I would absolutely LOVE the ability to run faster (for the love of god please?! ;3 candies?) I do personally believe that if it the pack already dodge rolls, why don't you go with the small sprint, very easy to add (I can post the like, 10 lines needed to do it at a small increase) it's able to be macro'ed to a gesture with chat commands. and can easily be set to a 5~10 second timer. I havent had a full chance to review all the other packs o.o but as far as 'assaulting' goes, without stepping on all the other packs toes. I think a sprint would be the best option. It's very low lag, and if the values are kept to a 20~50% increase in speed.. its not enough to be rediculous, but its enough to notice the difference. Also a sprint would thusly increase prim jumping height (more force at a prim = more force off the prim) also increasing the distance one could jump by roughly the same % of speed increase thusly allowing for access to area's otherwise unaccesable without prim jumping or a jet pack. I think that hands down a sprint + dodge roll would be a good addition ;o.
