Either a lucky or a unlucky spawn after an engagement could decide the game for you or the opponent.
Such a luck factor doestn suit competetive gaming.
Agreed, however current solution also don't fit into competitive gaming.
Look at it this way, when you are sunk you can show up to battle with new ship
in about 15 seconds. And if enemies are still spotted, and they usually will be
as they are engaging your allay, you can choose to pop onto their blind spots.
It means that getting destroyed, while still costing you point and moving closer
to ultimate defeat, provides you with short time of tactical advantage.
In competitive games you shouldn't gain any advantages from loosing
unless you think about sacrificing units to achieve long term goal in strategy games
but GoI gameplay type don't really fit this sort of tactics.
I think that base system will fix that problem as each map will have sort of safe spot
where you can count on your temmate spawning close, although sadly this solution will
probably make camping more popular.
Also like Dutch Vanya said, it should be optional at least until tested and refined.
