Some of those are really annoying/frustrating, and I totally agree that they need to be dealt with.
Others, I really don't see as a glitch...
I use fury. I am not trying to "glitch" or unfairly "lag" my opponent to death...really. I'm just using the strongest weapon in my personal arsenal. Isn't that why I built my cannons in the first place?? Why take that away? Half the time I lag myself with it, so I'm not seeing how this is an unfair advantage.
As for the ability to take either side...once again...I see this as useful, not harmful. I
like the ability to be with a friend, regardless of side, and to change sides when suddenly the side I'm on outnumbers the other side 7-2.
And spys... well, my own husband has, on more than one occasion, left my ship, launched his own on the other side, and come after me becasue he wanted the high bounty. I've sunk him... and I've been sunk by him. lol
We call that fun here.
