If you know, post it below. I just hit 100 kills and am wondering if I'm going to have to Auraxium the darn thing to get the titles.
Yeah, I don't think I'm the only one disillusioned by the fact that many of SOE's holiday events (with the exception of the cool snowman event) are based around "It's an event! Give us money to participate in the meager offerings!" Snowball pistol (which never had its sights properly calibrated), fireworks, winter holiday camos, last year's St. Patrick's Day camo, the Anniversary bundle (which was basically a super expensive camo + 6 month boost for many more experienced players), and now this. It should be a good chance to throw some fun into the game to encourage people to play--a holiday event also has the bonus of not totally breaking the game (like the WDS event). It shouldn't look like a shameless cash grab, especially if you're trying to hold/bring in new players.
These are the titles: Heartstring = "Sweetheart" Blackheart = "Hater" (Judging from the screens posted here: http://www.reddit.com/r/Planetside/comments/1xudqo/will_you_be_my_valentine/)
Got gold with the Heartstring. Finally got the title one kill before. Bugs. Bugs everywhere. Oh well. I guess that's to be expected. (3 kills from getting silver with the Blackheart.)
