i have over 2000 matches played on my account, and i have seen maybe 10 varus's.
its quite apparent varus lacks something because nobody picks him at all, and hes really not fantastic
the issues i notice is his ult truly really is only effective vs one person and mainly used as a peel.
in tank meta even with % damage i dont see him as fantastic unless hes played as apc varus.
he needs buffs. even if they're slight buffs. i would like to see varus played more, hes one of the more interesting looking and played out adc's
