@GraveledStoopid  Thistle Missile and Time Snare both make Rose a viable choice. You can also pick Super Savior, revive key teammates like a Sunflower, and when you're in danger you can Arcane Enigma while also still reviving others. You will have the time to pull back and regroup with other teammates if necessary.
There are things that people don't get about Goatifying:
- Goatify can remove overheals from zombies.
 - It can stop health regeneration. (needs confirmation)
 - You can spawn it from behind walls, but you have to be slightly a bit far and not hugging walls or objects when doing it. Otherwise, the goats will go upwards. (possible bug?) What that means is, you can Goatify more than half of the enemy team contesting on an objective while being behind walls.
 [needs testing] It might pause enemy cooldowns while they're in Goat form. Nevermind, goatified targets still have their cooldowns ticking. I personally tested it with split screen with All-Stars. The cooldown didn't stop for the shields after converting him.- Goatality increases the duration from 7 seconds to 10 seconds. This is useful when stealing batteries from zombies. You can goatify pesky Engineers around the batteries for longer while your reliable amazing teammates get the batteries.
 
To some people, it's a silly ability that seems useless. But it actually has many benefits.
(everything mentioned above is based on the initial release, I'm not 100 % sure about this October patch.)
You can also contest on objectives while in Arcane Enigma. Makes her a good choice to hold off objectives while teammates arrive during overtimes and become part of the problem of "longer Overtime periods" lol.
Rose might not be the strongest DPS-wise, but she is very useful when playing around others.
I did some "personal experiments"... I was following a Chomper, speed boosting him when he swallows and revive him when he's down. I try to Jinx the targets he tries to chomp. It worked nicely but sadly, in this game... everyone wants to get kills on their own and no one wants to play around others. Also, sometimes you have to do everything on your own because most players in this game have their own personal vendetta going on.
