Guild Wars 2

I understand that currently we have a killstreak in form of 25stacks from sigil.

I was wondering if Anet could implement a new kind of temporary killstreak rewards.
1) Similar to Transformation hit-streak, maybe we could get crowns or aura or new glows around the body for having 100 killstreaks in wvw or maybe 10 in pvp. It is just for a sense of achievements.
2) Things like /age, /deaths are interesting statistic to keep track. Perhaps we could have one for killstreak too.
3) The whole idea of killstreaks is to encourage more open field fighting, more exciting and competitive gameplay and satisfaction. To encourage people to continuously fighting, maybe have a time limit for the killstreak rewards before the special effects are gone.
4) Initially I thought of rewards for stats but I figured it might be OP for servers with bigger numbers. With these additional stats, it would just mean that they are tougher to kill. That’s why I suggested rewarding merely for the looks. =)

It’s just a suggestion that I thought of. Of course, there are many disadvantage/improvement that could be added to the idea I mentioned.
Feel free to discuss about it. Who knows, Anet might look into it if we continue to throw in interesting ideas.

One thing id like to add is this would not be very practical in WvW..
It already gets slow with all the particle effects flying around, this would likely make it worse (referring to the glow).
