Here's why...
For all those who enjoy their "free-form" targetting in Elder Scolls, you're in for a real treat now that Zenimax removed Tab-targetting... I know free-form targetting is fun in games like skyrim, where the mob conveniently sits in front of you or moves around a little bit while you whack the crap out of it free-form style, but have you ever tried to do that in PvP?
With free-form targetting in PvP, you'll have the utter enjoyment of having idiots jumping up and down, and spinning in circles around you, sprinting and zig-zagging all over the place, and otherwise being [censored] in order to not get hit. And why shouldn't they? Afterall, they'll be getting rewarded for it won't they???
But most of you Edler Scrollers don't even care about PvP do you?? You're up in arms to get them to change it so you can buy the game, blast through the PvE, and then put it on the shelf, while wrecking the game for all the REAL MMO'ers who are actually willing to keep paying for the service that Zenimax is offering... So, taking your advice will destroy PvP, and ultimately be the games down-fall of longevity, but that's OK, so long as you guys can blast through the content, and then stop paying the monthly fee afterwards.... Kudos. Except that $300 million was invested into this game, so when it goes belly-up on account of the MMO'ers not wanting to stay and support it, that money will come right out of Elder Scrolls 6, (if they're even is one), so enjoy...
