I think the cannons were fine as they were and I dont know of anyone crying for them to be nerfed. I guess it might make for more safe spots for ops like the little hill part near ravens base might be out of range of cannons now if so that would be a nice boon for blue-team. (You could actually shoot from there but its tricky and it was slightly in cannon range)

Also im glad they fixed the fat chocobo table chronometer I was worried for a second there, or maybe 4 seconds I dont know my clock was broke.
