Re: Alien flower
You know, there's a surprising number of characters which are best played in some counter-intuitive style. It's been awhile since I was the Alien Flower but I remember trying to figure her out, and she is very awesome at Garden Ops.
I was leveling up my Engineers to Super Elite just over this last weekend and I had always been somewhat frustrated by the Sanitation Expert and the Plumber; I could do okay with them but I knew I wasn't using them to their full potential. I know that some of the Engineers are better at indirect fire, letting their Splash damage do the hard work but those two were just tough to play even with that tactic until I almost stumbled onto the fact that they excel at true indirect fire while trying to help the team subdue the defense while not letting a BBQ Corn vanquish me.
The shots of both the Sanitation Expert and the Plumber can travel in a high arc so it's possible to bombard the Gardens from behind cover at longer distances when you can't even see it by shooting upwards and letting the shots fall into your target area and dealing Splash damage to grouped Plants. The tactic works best in Turf Takeover of course since you can't always see what you're trying to hit but when the defenders are trying to protect a capture point it's the perfect way to collect Assists and the occasional direct vanquish.
The Alien Flower has that same sort of learning curve involved with her Spore Cloud shots. It's no wonder that I don't see her played all that much now that I think about it, or any of the other characters which need an odd or different style of play instead of "Charge Enemy- Aim Straight and Shoot" to be effective.
