Approach target head on at full throttle (cloaking optional), charge torp HY @ 17KM and CRF @ 12. Open fire @ 10KM with torps/cannons and proceed inbound keeping cannons buffed and launch single torp when able (OR if torp scatter fire cooldown is complete- CHARGE and FIRE), fire single if able and still outside min range. Overfly target while reinforcing forward shield and recharging torp HY, turn opposite targets turn to re-engage if he's still alive.
...And pray your teammates don't drop a rift on your target as you overfly.
Reverse HY and scatter sequence (above) for multiple targets.
1) Does Cannon Scatter have any advantage versus a single target? Will it do more damage since all the "scatter" is focused at one enemy?
2) Armitage or Multi-Vector Advanced Escort when I hit Vice Admiral?
yes scatter volley does add dps even on single target, but less than rapid fire ofcourse. similar to torpedo spread and high yield.
and i would tend to armitage, but both are good...imho armitage has the edge though
the attack vector beta (it hink) is really the best...enhanced firepower + movement is really great on that ship. The problem those attack vectors have is the cooldown. If you die you feel gimped, since you can't switch into one right away.
i think in a MVAE you can make good use of the high power levels and take for instance a dmg sci ability like TBR or grav well1, at max power they are great CC and dmg boosts.
but so is a vent warp plasma 1 on the armitage etc..
it's really hard to tell...if you have a design preference, go for it.
