I (and a lot of committed PvP'ers) do not need cannon meat. We need killers. Dyed int the wool, killers. Cold, ruthless, methodical and thorough (I'm wondering if anyone will catch the reference... =P)
Seriously though. Cannon fodder is one of the problems of casual PvP'ers. Every death costs the team 5 pts. If you die multiple times, or at the very least don't match your kills to your deaths, you are sinking your team into a hole they can't dig their way out of with just tomes. Cannon Fodder is unnecessary for PvP'ers. We need killers, and we need smart ones that know it is best to work together and focus down targets as fast as possible.
Funny fact about PvP that most players don't seem to know: You can win matches without defending a single tome so long as your team is consistently murdering people. That means staying as a massive mob and zerging down targets. The more tightly packed a mob you are, the harder it is for defenders to pick out specific targets in the group. They end up auto targeting pets or tanks, and healers have an easier time keeping up. You almost always fall behind at the beginning of the match, but also almost always end up winning by 200-300 pts by the end. Unfortunately, this only works if the ENTIRE team commits to it, which almost never happens because most people are too scared to attack, or, worse, are lingering at the spawn point and hoping no one will notice because they're really only there to collect their pay stub and move on.
Ps. Your comment about PS4 targeting is accurate. So far, The ONLY downside I've had to playing on PS4 is that the targeting system is sluggish and difficult to cycle. You can fix this by setting up a mouse and keyboard to your system, but you'll still have trouble picking out targets in a tight mob. There's just too many names to sort through, and people are moving too fast. Auto targeting seems to focus pets and tanks before squishier targets, but it directional, so it can be worked. Targeting will try to lock on to the target that is closest to the center of your line of sight. Try the circle jerk to get the target you want. I am constantly disengaging targets with O and re-targeting with X after a slight camera adjustment to find the target I want. I Don't think it's something you can work as a healer, but, with a bit of practice, you can work it as a dps/tank. I've gotten pretty good at it now that I've had some practice.
