I love ground combat. I got that shiz down to a science.
That said, my experience in Pug PvP has been grim. I can hold my own, but I will in the end always lose to kit-switchers and consumable-exploiters. That simple.
Kit swapping is fixed for the most part, there is still swapping for cooldown reduction, but that's useless on certain kits. Also, if tactical initiative is up, by the time you fall back out of red alert to swap, the cooldown is over anyway. It's still a problem, but not as much as it was at one time.
Now consumable exploiting, you mean hypos vanishing off your tray? You're blaming that on the players you are fighting? Ok, that doesn't even make sense, players don't have control over your tray. It's affecting space batteries the same way it is affecting ground consumables. It's also getting fixed this week.
He's probably talking about food items. You used to be able to stack multiple items together when the benefits from those we're supposed to be like tribbles. One type at a time. That was fixed a long time ago though.
