As Cat said, the Gallente Assault in PC really doesn't hold up due to a variety of reasons:

a) To get any kind of decent HP you're going to be moving as slow as a heavy. If you want to run heavy, run heavy, don't run Gallente Assault.

b) Unless you're running armor repairers (in which you will die near instantly) you're going to be forced to have some sort of logistical support like rep hives and repair tools. Pro-tip, repair tools are uncommon in PC because it takes the gun out of the player's hand. It's better to just die and respawn with full HP than put two players out of commission until you're healed up.

c) The reduction to PG/CPU on hybrid weapons is nice but your options are very limited. Assault Rifles or Rail Rifles being the only weapons of value as you're too slow/profile too high to use a shotgun and all the other hybrid weaponry just aren't up to par (PLC for instance). There are also no hybrid sidearms with which to make use of this bonus.

d) In the event the situation changes and you are being murdered by combat/rail rifles (the FOTM currently) there is nothing you can do if you don't have another suit to utilize.

e) You're practically forced to use damage mods because shield equipment doesn't sit well with only 150 shield base.

And Ripper, Caldari Logi is still the master race in PC. Brick-tanking it is a hell of a lot easier and you'll wind up with comparable EHP, often times with faster speeds than the Gallente Assault running armor plates. More PG/CPU, more slots to play with, more equipment and a much faster recovery. The only real drawback is no sidearm.

I've been running Proto Gallente Assault since Uprising was released. Trust me, it's not as great as it looks on paper.
