increase invasion's champion select time

so unless you have a 5 man premade, youll suffer this problem too you dont know what to pick besides at the last second then the 5 seconds they give you isnt enough time for masteries unless you premade the masteries for every champion but i just use 1 mastery page, i just clear it and make a new one but especially with lag i cant set the masteries on time so i go in with no keystone or something
