You mean "harder and unfun"?
I like Bursa because without it I think Corpus is way too easy and "boring".
Now you have to hack to rip off the alert or bring a strong weapon into the mission.
I love the fact that the standard Corpus loadout is near-useless against Bursas. I hope they do this on all high-level missions, to force players to develop more balanced loadouts, and to force cells to coordinate better. It's great seeing four Tenno with Ice and Electricity only get annihilated by Bursas.
That said, the Bursa is hard to beat, particularly when you get multiple ones. But that's part of the challenge.
Challenge ?,play today inter..,sortie,have plenty of bursa,this is no challenge when boring,you run and die non stop.
^ I didn't die once in this mission. This mission even had Nullifers, so what was your excuse?
You have to improve yourself or don't do Mission above your skill.... especially sorties (this is a reason why I don't play public games...)
