I did actually, but I think it's too limited in either case. Spike wave is expensive a spell, and the effect is limited, whereas a lot of other's stun/slow effects are cheap/easy to execute. Probably ground spikes sees too much use to have entagle integrated into it, but I think a whole other spell is going to be detrimental.

QOT is already ridiculous 2v2 if played well, though 1v1 anybody can run/TP from her I suppose. The lack of stun/interrupt sucks (just like it sucks for fire TB or Regulus though he can make up for it to some extent with snipe/mine slowdown). Those thorns that slow people down could be buffed by another 10% or so at max lvl, and it should go wider because it's a bitch to aim.

I do not play her in this manner.  Once I am in combat I try to avoid changing forms as much as possible.  If i am going 1v1 with Sedna then I know beforehand that I am not going to outlast her.  That's fine.  I'm either going to try to burst her with open form (unlikely but it can happen if she overextends) or i'm going to retreat.  That's it.  I don't think this is a problem.

Queen's advantage is versatility.  Her disadvantage is that she can't do everything at once because she has to change forms.  She is a serious powerhouse offensively when she is working with her team, and she is tough to kill when she plays defensively.  Just because she can't do both at once doesn't make her bad, it makes her have to plan ahead a bit.

Try playing a few games just staying in open form and playing cautiously.  It will help you figure out what you can handle offensively.  You'll find you have a lot more mana once you're out of the habit of using shield which will help a lot with using spike wave effectively.  When you go back to playing with a build that has shield you won't end up relying on it.  You'll find situational uses of shield, but otherwise you'll be setting yourself up to play offensively with your teammates.

Yeah, I guess I usually focus more on her support aspect than her powerhouse aspect. When it comes down to it, her open form abilities seem fine. I just find her closed form abilities, with the exception of shield, to be lacking. Shamblers are not that great, and seem to have pathing even worse than most other minions. The exploitiation finale on the shambler tree is a joke (does the same thing as lvl 1 gold upgrade on citadel). And while the munch ability is nice for survivability, I think its associated dmg range is so small as to make it almost neglible unless you give specific move orders to minions prior to munching them. I would actually like to see the health gain from munching dropped slightly in favor of increased dmg and dmg radius. I would also like to see the shamblers reworked a bit so that they are used more often.

I think QoT is pretty strong.. but a bore to play. She excels in the support role, much more than Sedna. She heals (more or less), reduces armor, slows, AOEs creeps destroys towers. She lacks the strong 1v1 killing ability and generally performs well if you're good at switching stances and sticking with a strong tanking character (oak, rook etc.) But she is BORING. Probably why most people don't play her.

Currently 2 seconds.

actually, I'm kind of disliking my own OP here. I'm seeing spike wave as effective, but usually for an assist, not an actual kill. her lack of armor makes her an easy target, but I'm not sure the stun issue is the problem.
