It's because GW2 PvP is so inferior to that of GW1. No point.
How much GW2 PvP have you played yourself to come to that conclusion? Did you play it enough to become competent at it, or tried out different classes to see what worked for you? I'm curious because a lot of GW1 fanatics simply write it off without trying it.
Skills that depend on equipped weapon sets, no way to build individual or team builds like in GW1
This is completely false. Once you start digging into some of the elite specs later in the game you'll find that many of them change up the fundamental mechanics and skills of your class, and this includes skills from your weapon sets as well.
And you absolutely can create builds to your individual needs or for your team. Show me 10 players who run Druid builds and I'll show you how I build and play my Druid very differently to all of them.
I'm not at all trying to say GW2 has better diversity than GW1, I'm not retarded. But to come out and make statements such as;
no way to build individual or team builds like in GW1
Just shows your inexperience with GW2. Being a top PvPer in GW1 might make you knowledgeable about that game, but that doesn't immediately make you an expert on GW2 systems. Because it's a different thing altogether.
