@Studman61 I agree with all your suggestions. I still think something needs to be done with Roses Homing thistles at close range, as for me they don't seem to hit when the zombie target is directly in front of me?
And also Sunflower needs more ammo or more damage, unless I can hit headshots consistently, I have such trouble trying to kill zombies when 1v1. Unless you can consistently hit headshots, by the time you get the zombie less than 25% health you need to reload then you're dead.
It really frustrates me that the's are the problems that I face as in any game I play I love being Support.
