I've rolled with Argonian's since Morrowind, my induction into the TES series. Origionally, I made good use of their claws they used to have, but have sense adapted a much less... feral, playstyle.
All my main characters, aka, my first's, aka, My Argonian's, are master sneak theives with insane destro backed up by Archery and classic sword and shield should things turn ugly.
Lemme tell yeah, against spell casters, Shield bash is your friend when you're a theif. Interrupts almost all spells. Assuming you can't sneak attack them that is.
Start with an arrow sent sailing down the hall, OHKO'ing the big bad, then Stab the guy who investigates in the spleen, throw him to the ground as I fire off a volley of Ice Spear spells with my offhand, followed by by Fus Ro Dah, use the gap to switch to dervish (dual wield), wade in like a blender with numerous dual charged attacks, relying on Histskin, Dragon Scale(legendary) and massive stamina reserves to fuel all the attacks. What's left standing I'll either shout down with firebreath, or a spell.
Completely differant strategy for Dragon priests though. Equip SpellBreaker Shield, Equip Dawnbreaker, pop Histskin, and wade in, shield bash whenever they look like they're waving their hands funny, and just chop 'em up.
Of course, having a prideful, confidant, Lizard man with the ability to breath Fire, and wearing Dragonscale armor, it all kinda screams Micro Dragon. All I'm missing are the wings xD
