I prefer not dying in the first place!
Spawning is going to prove to be one of those tactics that is overlooked. For instance:
Say you want to take a certain base. You know your enemy is going to prep the base you want to take. How does he know you want to take it? Carefully dropped hints disguised as "intel". He then prepares to have the manpower available to defend that base or territory. Part of that is the mentioned APCs for respawning. Meanwhile, we are really planning on taking a totally different base away from the "hinted" at base. The enemy then has all his assets and spawn points at the wrong location enabling us to waltz right in and q0wn them.
By the way, this tactic is copyrighted. hehehe
