We all know there's quite an imbalance between Shield and Armor vehicles, the winner in all areas being armor. However, this is not a post about making it balanced, but simply a temporary measure until CCP has time to work on the imbalance.

The current issue for vehicles is the lack of powergrid. In a Gunnlogi, currently I have two of the best powergrid expansion units for 15% increase apiece in both of my lows and still don't have the pg to fit two heavy extenders and a heavy rep, even the supplemental ones which use less pg. I even did a theoretical fit, using the lowest pg a Tank can possibly use up (Standard missile turrets) plus the two pg extenders, currently with lvl 3 in Vehicle Core Upgrades, and I still cannot fit two extenders and a rep. I even left the other two high slots empty.

My request is simple. Vehicle Armor Plating gives a 3% decrease in pg consumption of armor plates. I request that Vehicle Shield Extension give a powergrid reduction as well in lieu of the current reduction to CPU it gives.

By no means am I saying this will fix all the imbalance between the two different tanks, nor will I repeat those arguments again here. But this is a quick fix until such time as vehicles get the proper attention they need. A little painkiller before the surgery as it were.

You're sorta right, in reality Shield is meant for Long Range combat, where armor is more in your face, tank all the things, combat. Problem is that armor with a railgun basically negates that advantage for a shield tank.

The point the OP is trying to make is that the Armor Tank can fit a Plate AND it's Nomral Sized Rep.. ie. Large / Heavy

The SHield Tank can EHP OR Rep, but not both.
