So the reason everyone hated/hates the cal logo is because it can dual tank itself into a monster, right? So the problem isn't with the suit. The problem lies with the nature of dual tanking.

So what if they made an inherent penalty for tanking on top of the current penalties? For instance, let's look at shield extenders. Let's have every shield extender make the shield recharge 20% less, so 5 extenders removes all shield regen. Harsh sounding, butiI'm only doing it to illustrate my idea. Now for armor, every armor plate reduces turning speed by 20%, down to being unable to turn with 5 plates. This is on top of the movement speed penalty for plates and whatever penalty shields will get, if any.

Sounds ********, right? That screws over single tanking too! So here's the kicker. Each race has a focus on one type of tanking. Caldari focus on shields, Gallente focus on armor. So the caldari would invest their time into reducing that shield penalty, and not care about the armor penalty. Gallente would work on servomotors or what have you in order to remove that turning penalty. Amarr and Minmatar would fall somewhere in the middle, both of them able to reduce both penalties, but not remove them entirely. Caldari would have no shield penalty, but take the full armor penalty. Gallente would have no armor penalty, but take the full shield penalty.

Now we have a dual tanked cal logo that turns slower than a rail gun. A dual tanked gallente would never recharge their shields until they died. This would make dual tanking completely unfeasible, and still allow amarr, obstenitely the dual tanking suits, still retain that functionality. The penalties and numbers are placeholders, just want to demonstrate my idea.

In summary, add in a penalty for tanking your suit, and have each race reduce their specific style of tanking (shield for caldari) penalty at the expense of having the other penalty in full.

Hope I said this is a clear manner. Typing on my phone sucks. Cracked screen.
