Soon be hitting 30, so not sure if worth staying with escorts or flipping over to Cruisers, but then since most of us will be getting Ent-F not sure its worth it? Thoughts?
The Ent-F, will be like, playing with a slow moving whale, which has about as much grace as a brick with arthritis, even with 2 RCS consoles, I don't see this moving much.
Also is there a list of what weapon type do most damage to races, so what kills kligons better, romulans etc?
All the weapons do the same amount of damage to each of the races. The basic difference is the procs that each type has.
Phasers can disable systems.
Disruptors can give a damage resistance de-buff
Plasma can give additional Damage over time.
Polaron can drop your foes energy levels for a short time.
Tetryon can do additional damage to shields
Anti-Proton can critically hit slightly more often and do slightly more critical damage.
STO is not like other MMO's where some enemies are weaker to (say) elemental damage, than slashing damage. The amount of damage the foes take depends on a number of factors, such as your level, the foes level, your energy levels, the foes shields, the rating of your foe and so on and so forth..
About the only weapons that don't follow the above are the STF [Borg] weapons which do additional damage to borg only.
Most players will stick with phasers as an all-around weapon (especially if you have a Galaxy-X, as it has a Phaser Lance weapon), some others like Anti-proton. But the basic jist is that there is no definitive 'best' weapon, only ones that are better in certain circumstances.
