So I just completed the main dragon quest. I play/ed a thief and in the last part of the main quest I noticed they are extremely crap

this build I have but I want something more open combat. As a thief its hard to sneak past the deathlords in the last part of the game and killing them on master difficulty is no easy task:)
So I have a lot of experience with this game, I want to start from scratch and do ALL the other quests before even touching the dragon main quest.
I dont think I want to continue as a thief, I am sort of getting bored of just sneaking around 1 hitting everything, hell I can even 1 hit a dragon, not a blood or frost, just a normal dragon
when Im in sneak mode with a poison applied to my daggers.
So I would like to play again as a full on warrior kind of character. I am trying to vary my gameplay and want you to suggest my next class:)
Should I wear light armor or heavy?
normal weapons or bound sword?
2h or 1h?
Stuff like that. Or tell me how you play and I will pick the one I like the most:)
Thanks:)
