I hate that almost all PVP ships require a MWD. (exceptions being specialised sig-tanking AB fits, 100mn AB gtfo fits and Stationhuggers).
When MWDs were introduced, there was much fanfare about it being a "burst use" emergency / combat initialisation mechanic. It was never intended to be something ships could (or nearly could) perma-run or use in so many situations, and it shouldnt be imo.
What would the following change:
+50% small MWD cap usage (t2 MWD = ~75 cap)
+100% medium MWD cap usage (t2 MWD = ~400 cap)
+150% large MWD cap usage. (t2 MWD = ~1950 cap)
(Possibly) remove the -25% capacitor penalty from all MWDs.
The idea of the escalating increase is that the larger the ship, the less common MWDs should be.
On top of this, certain ships (some of which already have MWD cap bonuses) would have increased bonuses to MWD cap to keep their cap use stable with the present situation (perhaps - all gallente blaster boats, quite a few minnie sub-bs ships and the typhoon, primarily, and one t2 cruiser for each of amarr and caldari).
