how to win in pvp:
1. be tactical
2. buy escort
3. take full cannons build, no torpedos
4. take 2 attack patterns and use them together (alpha+omega, beta+omega..)
and no sci or eng even with superhero build can threaten you.
guide for sci:
dont play sci
guide for cruisers:
dont play cruisers
blablabla, yeah, i had really bad game against 3 such escorts a while ago and am angry. the build up there is 3 times better than all others.
