One reason developers resort to PvP mechanisms in games is that it is a lot less programming, testing and work to create. Companies like Bethesda who craft full-fledged story-bases games are a rarity nowadays due to the enormous costs to make that sort of content versus the quick and easy route of just slapping together some PvP mode.
That said when this game first started PvP was the minority of activities and I really preferred it that way. PvP in this game is inherently flawed in so many ways. Matchmaking for GAC or TW doesn't factor secondary speed mods at all and it seems that G13 and zetas really don't weigh much if GP is all that is factored in.
For PvP games, which I still don't like for the most part, I prefer ones where player tactics, strategy and skill outweigh random elements like who has lucked into the fastest secondary speed mods. When mods were introduced, in my opinion, the potential for interesting PvP died.
