I'm a little disappointed with how few science officers there are. That generally means mine will be forced into a healing role.
Not the first time this is happened with my chosen classes
Admittedly, a large part of why I chose science was that it appeared to be the least popular, so I hardly have reason to complain
No,you won't. Not as the game stands now. Healing (other people) is a waste and buffing them almost as much so. Exception: PvP ground maps. There healing can make a very big difference, moreso direct heals via medical tricorder.
Science PC's can do very well if they think about their class in terms of *debuffing* as their attack strategy. This prevails in PvP especially. You simply have to ask yourself if that's the playstyle you want, and I'd wager it isn't for most people... but I think it would be quite effective.
