Tank raid non heroic

Cmdr Luke can put the ability block on Grevious which prevents him from getting the triangle of doom. Also Thrawn's fracture prevents it too. You have to get the timing right to keep Luke's ability block on Grevious so the triangle of doom never appears. Only use Vader's light saber throw if Grevious is fractured and Luke can ability block before fracture expires. If the timing gets messed up and Grevious gets the triangle of doom I open my app view screen, close down swgoh and then restart it to get the score I want.
