The perk system is fine, I don't have a problem with it. What I would like to see is more skills, or perks, for further specialization. It could be improved on greatly.
I agree with the last part, but I think the perk system could be improved without adding more perks. Instead of the very one dimensional magnitude increasing Perks and ranked perks, I would rather they put in Perks that grant you unique abilities or spells that further add specialization and add more tools in your belt. Shield Bash, Silent Roll, Eagle Eye, Impact etc. are fantastic concepts of Perks - the problem is they are few and far between. As far as combat goes, there just isn't enough. There are not enough defense tactics or offensive tactics you can use. For spells, you pretty much chain spam Incenerate. For melee, you either assassinate or power attack/spam elemental frenzy swing. For Archery, at least there is some aiming but it is pretty rinse and repeat. Blocking is great! Having the ability to actively block attacks effectively is fantastic. Dodging however really is non existant outside of taking 2 steps left or right or backpedaling to avoid an attack. Your other defensive tactic is to run and line of sight. Pretty shallow.
I think Perks need to give you more of a sense of your character which they do not really outside of the damage you deal or the magnitude of the ability - which could have been accomplished in a much better way (such as selecting these skills from the start or at trainers to become your Primary/Major/Minor).
