So, presuming that one is smart and actually invests SOMETHING into having enough health to survive certain unavoidable big hits, it is somewhat difficult to softcap stamina as the only way to gain additional stamina is to be a redguard or imperial. In addition to stamina being the hardest attribute to build in the game, blocking, roll dodging and cc breaking all cost stamina.
The problem with this, while being thematically correct really hinders resource management for stamina based players. So in pvp, break cc is vital - as it is just about anywhere, however when i use it, that is HALF of my stamina pool gone. I suddenly can't risk using any of my weapon abilities for fear that i may have to block a powerful ability or roll dodge out of an immobilize. Having invested little into magicka all of my class skills are relatively impotent compared to my weapon skills.
So this is clearly a complex issue and from a thematic standpoint is difficult to alter. I have given it a lot of thought however and would like to share my ideas on the matter.
Suggestion 1: A BASE increase to the costs of roll dodging, blocking, breaking cc, bashing and sprinting with cost decreasing dependent on investment into stamina as well as certain skills. To compensate the effect that would have on magicka based classes - give options for magicka based alternatives (blocking/breaking cc/bashing with a staff cost magicka - have the resto staff passive negate 50%/100% the cost of blocking a spell instead of restoring a small amount of magicka), change bolt escape to work like roll dodge but with a POWERFUL effect on successful dodge of attack (instead of just pretending to be agent smith). Doing this would level the playing field as far as everyone would have a similar amount of Resource management to deal with, instead of magicka casters simply spamming abilities without having to spend a drop of stamina on anything other than blocking/breakingcc/rolldodging/bashing
Suggestion 2: sensible magicka based alternatives: have the stealth resistance mage light morph allow you to break cc by double tapping block, or any magicka based break cc alternative. have a passive in the world tree that everyone has access to 'protective ward' - magicka based block that can be bound to a key, and maybe instead of giving more spells the 'interupt' effect, have the stamina cost of bashing restored when knocking down an enemy by exploiting the interrupt. - This would bring stamina investors back into a level playing field of resource management by being able to leave the magicka pool mostly untouched for use in saving themselves.
Suggestion 3
Make the cost of breaking cc in medium armor cheaper, change the roll dodge passive in the medium armor tree to read "Refunds 50/100% stamina cost of roll dodge when successfully avoiding an attack, (i mean you already do a little dance when it happens - so the game knows when you do so) also putting a small cool down on roll-dodge so that one can't simply spam it in pvp to never take damage and never run out of stamina, refund the cost of bashing when exploiting the opening created. This is my favorite suggestion - mainly because of the satisfaction one would have from playing skillfully as well as keeping to the flavor of a leather bound rogue fighting clever and fighting fast.
