Personal Evaluation.

Just some evaluation.  Need to know everyone's preffered roles as well.

Myself (Sark)- Preferred Role: Mid
Good at - certain top laners, tanky junglers, and some adcs, just about any mid.
Bad at - supports.  Fizz.  Weaker junglers. Not lagging out.

Legini - Good at - ADC, some top laners, certain supports, some mids.
Bad at - jungling.  supporting a bad adc.  Assassins.

Freccia - Good at - Top Lane, some supports. A few junglers.  Some adcs.
Bad at - Mid.  Other adcs.  Other junglers.

Mark - Good at - Supports.  Some ADCs.
Bad at - not being a good support.  Jungling.  Assassins.

Zoygo - Good at - Jungling.  Some supports.  Assassins. some adcs. A few top laners.
Bad at - Other adcs.  Counter jungling (havent seen a lot of it when i've played with him). Sustain Mages.

Acuite - unknown (working on it, maybe he can add something?)

Ikaros - unkown (haven't played enough games with him to know, perhaps he can elaborate on what he prefers and is good at?)

ek Devil - Good at - Supports.  Support Carry.  One or two mids.
Bad at - getting early game kills to the adc (usually by accident), Jungling (no experience as far as I know), assassins.

Peavey - Good at - adc.  Some supports.  (Haven't seen much of him so still somewhat unsure).
Bad at - (unsure.  Have only seen him play 2 roles so far).  Jungling.

This is a work in progress.  I do not mean any offense by anything I post.
