i've no idea about the usefulness of the eva's saint tree, it says it's untargetable, but if it's destroyed as easily as their tree currently is, it'll be the most useless class of the 3. the 2 others win some pretty skills, a 100% crit rate on most heals for the cardi, a zilean ult an automatic salva if you're killed while the buff is in effect. for this last skill, the question will also to know if you "die-->auto-insta-res-stand-up-lazy-***", or if it triggers before you die (meaning it can be used in og/coc, meaning se will be even harder to fight...)
