Destroy the bomb before detonation?

[TKF]

Well about this, the bomb in late game is very easily destroyed. I tried to put the bomb several times and failed cuz it was destroyed instantly. Both trader and bomb get destroyed easily by a super foe. Also the creeps alone is able to remove it effectively too if you plant it right after a creep wave. Also you waste your gold for nothing when the bomb gets destroyed many times. Weapons/items is a permanent solution which is better than a bomb, especially the risk of getting bomb destroyed.

btw does the bomb benefit from armor upgrades?
