That other person/group would not have gotten the lock, unless they did at least the appropriate percent of damage on it for their level range, and discounting the lock, they had to do more damage than you did after respawning - so they obviously did more than a single hit.
many people feel that players solo-killing a boss using restos, and other players as pawns while you respawn, is a completely inappropriate and unfair way to play a game. I cannot see any other way a player can Solo kill every 6* boss up to lvl 149 being a char in the 160 lvl range.
So, yes, the fact that you cannot continue doing this must be very annoying...
But imagine how annoying it has been to those other people wanting to get a boss kill in occasionally, but had to just sit around watching one or two players dominate every boss with plat items, and hope those players might sell the drops.
On the plus side, with some small adaptation, this kind of thing shouldn't happen to anyone more than once...
one of those "corrupt beta testers"
Ok so first of all, the person does not need to do anything more then hit the boss once, or use on spell on either the boss or someone who has any aggro before the person killing it does. Second of all, you do not need plat to kill 6* bosses solo, you need strategy (my sig is out dated). Third, i never sell my drops, i give them away for free and if there are other people there before i arrive at the boss i always help them kill it and let them keep the drops. If anyone asks to group, i group (unless they are a known scammer). And idk what corrupt beta testing has to do with this.
The simple fact remains that target lock creates many more problems then it solves. Make it simple, get the lock at a set damage percentage (20% perhaps) and only reset if the boss resets. Then if the boss resets, the other opposing group (if there is one) will have a chance to kill the boss themselves. If not, the original group is free to try again. Making a set percentage at which the lock is awarded will take away the guess-work and the use of lower levels in a group to gain lock sooner, along many other problems.
Simple and easy, the lock doesnt need to be and shouldnt be as complex as it is now.
Enjoy the little things in life...
One day you'll look back and realize they were the big things.
