Did the guards get buffed or maybe something else changed in U35/U36? I used to be able to go to a mine/farm/lumberyard, run up the tower, and use a fire ballista to kill the 4 guards around the flag in 2-3 hits, now I'm lucky to kill 1, 5 hits might get me a second, but the 3rd and 4th guard seem immortal...
Thanks
