Campaigns are a bit odd, sitting alongside the existing mission structure, but they're a welcome addition in terms of providing new things to do.
I feel that the individual tasks have a good range of difficulty, but overall they're perhaps a little too easy to achieve. As always with goals that are of the type "torpedo 6 ships", etc., they may have a negative impact on the natural play of a game, but overall I think it's a good thing to push players into play styles with which they may not be entirely comfortable to begin with.
For example, I'm not a destroyer player, and I favour long range engagements hence my liking for the Tier V ARP battleships (battlecruisers) which can yield excellent results in Tier V and VI games.This leads to fairly passive play as long range bowls isn't always very rewarding. Since finding a number of flooding and torpedo tasks to complete, I've been playing my Emerald differently, with at least some success. Still not a fan of DDs.
Which leads us to the reworked Japanese DD line. Anyone playing these care to comment?
