The new guys itching to go
Now I know I only have the perspective of my own view in this e-fed, but like Ty said, one to two RP's are about the standard here. 90% of the people here have trouble posting one RP, let alone a series of rebuttals and counters that you are proposing. Ty posting this early is a very rare occurance. I look at RP's like a promo before a match, something that tells a story, talks about the match, opponent, and possibly the feud.
The success of RP's in this fed is based on writing skills, how well you portray your character, how engaging your story is, and how you talk about your opponent. They are not all about countering what the opponent says, and constantly one upping them into submission. We don't see Cena and Orton doing 4 or 5 countering promo's before a single match, that is done over the course of weeks building to a PPV. So in essence, one RP where you effectively call out your opponents flaws and weaknesses and assert your own strengths and why you'll be victorious is much better than 4 or 5 RP's where you may just reiterate the same points with maybe one or two bits of additional info.
I'm not in charge of creative or a part of creative. The best person to inquire about how this e-fed runs is Lee. I'm just telling you that this is kinda how this e-fed has run and if you want to suggest changes, that would be great, but if you're looking to post 3 or 4 RP's a match I'm telling you you won't find many others able to do that. And unless all the RPs are on par or close to your best one, you may not win many matches. Quality over quantity has been the golden rule here.
