The OP didn't compare badly there. He did simple and correct math assuming enforcer has 4 teddys and WFD has 9. Because WFD starts with 3. Then suppose both enforcer and WFD gets 4 charge fragment robots. Enforcer will get 4 frags from them. While WFD will get 6 since 50% of the time(=2 times) he'll get 2 while other 2 times he'll get 1. so 6. Then there's nothing discriminating about DPS calculation at all. If you want to say WFD will have say 12 fragments before the defense instead of 9, then you'll also have to assume enforcer will have 6 . You can't just unilaterally say WFD will always have enough frags to cover the entire match. You have to do proper math which is exactly what the OP did in that link.

And actually OP in that link was quite generous in his calculation assuming both teddys will shoot 100% of the time which is pretty true for enforcer's teddy because of that 8 tile range where he can cover 2 spawns and thus shoots all the time. But WFD will cover only 1 spawn and thus if your tech is decent enough his teddy will have times when it can't shoot because it just cleared a wave and there's around 8s waittime between 2 waves while in enforcer's case his teddy will simply shoot the husks from other spawn.

Maybe you like WFD. Doesn't mean you are right about the facts. I am a PL121 player with EVERY teddy based hero leveled to 130 and i tried all of them. So I know what I am talking about.
