I'm sorry, but Large Base and Arc Dodger are two words that don't go together. A large base cannot consistently get out of arcs.
Have you ever actually flown against a well flown Falcon with Engine upgrade? trying to keep 5 ties on target is nearly impossible.
Additionally to all those saying "if you block then you get 5 focused shots" well no you get 4 because the blockers not shooting, once you loose a ship if you intend to block you only get 3 ships to shoot, again assuming they all actually have arc.
Having flown Whisper + Mini Swarm on the weekend at a tournament my only loss was to a well flown falcon, with 3 Zs flying interference there was no way I was ever going to block it. Boost on a large base ship with the 1 turn on its dial most certainly mean it can arc dodge.
