The Caldari Logi specifically needs to be looked at. Most people right now are running them as beefed up Assault suits because they have the most customizability of any suit in the game. 5 high and 4 low slots on top of the most CPU/PG as well as the best racial bonus make them able to do anything they want. I don't understand how CCP let something like that slip through the pipelines. You can literally do anything you want with that suit, even going as far as matching a heavy's EHP while still being faster and able to carry equipment.

Looking at that suit makes it seem to me that CCP doesn't even bother to do any internal testing before releasing. Every top corp in PC that I've faced steamrolls the battlefield with their Caldari Logis of Death. Some of them don't even bother to carry equipment, instead choosing to stack Complex Extenders, Damage mods, and Shield Regulators at no negative cost to them. All of the suits need another balance pass and CCP needs to release the stats before they release another monstrously imbalanced suit. It doesn't matter one bit what CCP intends the suit to do, it's what people will do with the suit that matters. As soon as people saw how incredible those stats were and that they weren't changing them, all the min/maxers flocked to it and started running God-mode Assaults with them.

Then on the other hand you have the Caldari Assault which has the most useless bonus (10% reload on hybrid at level 5). So putting ~2.5 million skill points into Caldari Assault gets you a worse suit stat-wise (4H/3L vs 5H/4L and way less CPU/PG) and a bonus which shaves off fractions of a second on reload (.3 seconds on ARs for example). Im so baffled by how they choose these bonuses.

Edit: And don't even try to mention a lack of sidearm as what makes it fair. I run Assault suits and hardly ever fit a sidearm on my suits. It's not necessary when you have hives, which the Logis can easily fit and still have room to mess around with whatever they want. For example they can put a CPU upgrade on the low and still have 5H/3L and run prototype EVEYTHING (equipment, modules, weapon, grenade, etc) without a hitch while still having >500 shield and however much armor they decide to stack on it. No other suit is nearly this powerful.
