I don't see why people complain about the spikes, I get to the flagroom with health at 3. Takes patience and coordination. The only thing that bothers me is the 2nd floor where it's far too easy for defenders to reach the flag room and unless those spikes shoot fireballs, it has no purpose.

The chains to flood the 2nd floor are hardly used since it takes a while and leaves you defenseless. Prefer switches (if 2 is too little, do 4 in each corner of the room).
