So, what do you plan on doing? What direction do you plan to invest your skills?
Let's face it, although you can "become who you want to become", properly spec'd players will always (almost always) come out on top in a 1v1 fight (assuming that both players are of relatively equal skill). Meaning, that a dual wield spec'd Nightblade in medium armor will more often than not, tear the face of of a resto-staff spec'd DK in light armor. It's simple game mechanics.
Do you plan on "being all you can be" or "being whatever your heart desires" (however worthless that may be)?
I personally have the need tear faces off 1v1 in PvP, so I will be Min/Max-ing to an extent (I don't number-crunch, entirely). I believe the system is set up so players have options like directing your focus on stamina based skills or magicka based skills and still being effective in either direction, but I certainly feel that creating certain types of characters will be rather dumb, and ineffective.
This is, of course, my opinion. How do you feel towards the topic?
