Baron And Dragon Replace Idea...
Instead of Baron and Dragon there should be an Over-Shield and Invisibility respectively. Mechanics similar to Halo 3.
Over-Shield(red orb) grants instant invincibility when walked over, until fully charged(~2 secs i think). then starts to slowly decrease(~30 seconds i think).
Invisibility(blue orb) fades invisible and only disappears momentarily when attacking, then fades back invisible when not(~30 secs i think).
I think they re-spawned every 3 minutes(that could be increased to like 5 or 7) from when it was grabbed @.
What do you think??
