Most people also seem to have forgotten that it no longer is a stronghold of potent infantry defending it, but outside of short time, a funny looking reinforcement bunker.
Instead of exploiting the fact that there is a lot of inf around it(from these unicorn tales supported by a total of zero replays) and using indirect weapons, they just prefer to REEEEE that the building is hard to destroy when you have no idea how to do it.
If I say its too difficult to counter it, and you say its easy enough to counter it, the onus is on BOTH of us to provide replays since we are both making claims. Where are YOUR replays?
There doesn't need to be a lot of infantry around it for it to be useful. Its plenty powerful as a place to soft retreat to, and the buff they get from Rally Defenses is the second most powerful timed infantry stat buff in the game(after the UKF officer charge).
As far as the buff duration goes, you don't need it to be omnipresent, you just need it to last long enough for critical engagements. And since it doesn't cost any munitions, there is no penalty for spamming it whenever its off cool-down and your troops are engaged.
