In light of the current patch after playing with the shades for a while I have to say the changes are a bit too punishing for the scourge. The necromancer has always had trouble getting people off of them, even before scourge and now its next to impossible. Even in Open world PvE its a major issue. If the goal Arena net was going for was to reduce the reliance of Sand Savant and to increase the player's requirement to actively pay attention they have failed at both.
Let me Preface this with the fact that I'm a rather strange player when it comes to necromancer and GW2. I don't like using Sand Savant unless I'm running as a healer. Even in open world. I like using demonic lore since it requires that I pay more attention to where I place my scourge and it forces me to aim more instead of just drop and forget with Sand Savant. I need to think about it. This wasn't a problem for me since I always had the means to defend myself in Open world and other game modes if someone or something decided to get to close to me. I needed to be extremely conservative with my shade placement too because too many shades would seriously damage my ability to fight, but it wouldn't cripple it. Well, now I don't have this active defense around myself and the shades are expected to be used in the exact opposite way I've trained myself to use them, along with many other players. Now, I'm not one to say that a player shouldn't adapt to the changes, however what I am going to say is that the changes to the shades should reflect this change in play style. So with that let me put my argument forward.
With the shades and their placement being a nessecity to the gameplay of the scourge I'll make a suggestion to further incentive players to take the other two grandmasters over Sand Savant which at the moment is the absolute best trait you can take, its not even close. Reduce the recharge of the shade charges from 15 seconds down to 5 in PvE and possibly 10 in PvP and/or WvW when Sand Savant isn't taken. Lets make this clear, you want us to spam the shades, let us spam them hard. We need to re position them and we are currently punished really hard by such a long cool down without the active defense around us. With the cool down this low it changes the dynamic of scourge in PvE, WvW and PvP, which would be welcome as opposed to only seeing the massive shade.
Players will need to adapt to the changes you've made and they shouldn't be punished for the adaptation.
For the F2-5 skills the pulse around the player has been removed as long as the shade is active. This is a mistake and i'll explain exactly what I mean. And I'll explain where I can agree with it and where I don't.
This is just a simple post addressing the changes. I would like to play this spammy shade style Arena net wants us to play, but we need the tools to actually be worth while to actually do it. This is my feedback from these changes. I really want to run Demonic Lore or Feed from corruption in WvW over Sand Savant. But as the balance is no, there is absolutely no reason you should ever consider anything over Sand Savant.
As always, I'm open to critiques and discussion. Lets get a conversation going. I don't like the changes personally, but I can get behind them with the right bit of retooling. Any thoughts or concerns? let me know. And Devs.... Seriously think about it.
