fortify homes: respawn timer on the materials feels too high. having to run around 60 seconds before you find a non taken material container isn't exactly fun.
evacuating: it's hard to determinate when exactly the citizens are 'saved' or if they need another gentle push in the right direction.
salt vampire hold: no immunty when using a hypo to get out of it. (surprise)
rewards: while I cannot judge what the romulan marks will be worth in the end is the amount of fleet marks rather MEH. getting 10 marks out of a 20 minute effort (during fleet mark hours as well) just doesn't cut it. large events (i.e. greater than 5) require some kind of dummy bonus.
edit: I wasn't able to use my operational assets as well! ,c
