I don't think S skills are what's limiting people from joining PVP. This is meant to be part of the end-game mechanics of the game, if it's made easier (in addition to every other thing people are asking for to be easier) there won't be anything really to work for as everything will be attainable easy and it just defeats the whole purpose of grinding to get better.
If you wish to compete with the big guns with full S and Mythic, you gotta farm like the big guns. I know it's not easy to do as some people only play for an hour or two, but if that is the case then they really shouldn't be complaining about making things easier and just be patient with the grind (I don't mean you by this I'm just speaking in general terms).
I'm just sharing my 2 cents and I know there's a vote option for this so no need to remind me xD. I will vote, and thanks for the suggestion anyway!
