Taliyah bug intentional or.....
Using your E W Combo on an enemy or waves doesnt let you Q for quite some time. maybe 2 whole seconds. So whats the point of bringing them to you? they just walk out or into their minions.
Remove this bug and Taliyah will be Decent... because she is still meh.
"How to Reproduce the Bug- Pick Taliyah Use E W Combo Try to add a Q right after and see that it takes a good while in order to cast the spell.
