That is speaking from experience of playing the game and talking with other people about tanking. While I obviously didn't speak with the whole data center, let alone all data centers, it is still a valid way to collect informations. Also do mind I've never ever told anyone that they are "not true tank mains", that is just what you made up after my rant. I very much support anyone who wants to tank and wants to play DRK, since over time the number of tanks will drop per usual. It is just not a role that most people like. My point was that it is purely ridiculous to alienate some portion of DRK players (dunno how many of us feel this way yet) for the sake of making DRK more accessable. We already had WAR and PLD as the easy tanks to play, now DRK joined them and the "skilled" tank is now GNB - though it's more strict than anything. More than anything however, the people I know from tanking seriously dislike how slow DRK has gotten.
That is your opinion and I very much respect that. However new tools don't mean much when you can't use them often. Plunge with charges is awesome, I'll give you that, but the rest? EoS is just a DA that now does direct damage and the usage dropped significantly, plus you need to spam it in a party buff window instead of using it whenever you can. Living Shadow... eeeeh, I just can't say much about this, others have already said more accurate stuff about it than I could - it's just a glorified DoT with a 2 min CD and has no interplayability with anything in your kit, hence a DoT. More blood is neat, since WAR had 30 every Path combo. Abyssal Drain eh... I'd much prefer the AoE rotation DRK had in SB than what we had now, so I'm not a fan of this one bit.
Now the "fantastic burst window" is what drew many WAR players away from him in 4.2 while drawing in new ones. This "burst window" was an incredibly hit or miss change. And to this day, the comunity is very torn about it, some find it awesome, some find it dreadfully boring to spam a single skill. So why would it be any different on DRK? Why did the sustained DPS change to burst? There is literally no reason. If the DPS was a problem, you very much could have increased the damage dealt by auto attacks to balance it out. Though I honestly don't get what you mean with your last line. It's better to not weave between SE almost anything rather than something like it used to be? But you do you.
Do understand that if someone didn't like or didn't care about SB BW, the job wasn't most likely for you anyway.
