Protect round is countered by Poison and Illusions but what can it do and who can it counter. The ability is good for abilities like laguna blade or assassinate. Long cooldown attacks that take awhile to use again and that distribute large damage.
PTR’s cooldown should be long enough to place on three to four allies at once. And her mana cost should be made to last so she can escape adequately.
There are only two uses for this ability countering attacks and abilities and escaping. Keeping people alive. Protecting: That’s the entire premise of the concept.
