It could all be totally fine, there are just a bunch of weird tradeoffs being made that people are naturally apprehensive toward. You give the flag carrier a (pretty weak) weapon, but he can't switch away from it. You make the flag carrier faster, but then you broadcast his location to everyone in the match, making him an immediate target. I mean, you always needed to protect the flag carrier, whether it was through direct intervention and killing his attackers as he's being attacked, causing a distraction on the other side of the map so he can sneak away from it, or by spawn trapping people so that their pursuit options were limited. Teamwork was always required. Now, with that waypoint that you can't escape by dropping the flag, some of those options are now limited.
