@RiotRepertoir-Context on kalista changes

Hey (: ,after reading the changes i couldnt help but feel kalista is going to be weak in season 6,her two core items where nerfed (bork and runaans) ,for runaans i wouldnt say massivley nerfed but kalista needs attack speed and lifesteal more than anything,which means now in order for kalista to have an effective build players will have to buy another as item after runaans(even worse now that jumps only scale with as) ,by doing this further delaying bt for more lifesteal and you waste the crit chance,does this mean well have to build kalista a critical strike build and sacrifice wat makes kalista unique ?it just seams kalista will be ineffective after these changes and i really would like to know whats the direction with her thx (:
