Definitely Tanksha is the way to go. Make it a 2v1 situation where you can burst the Ringo down. Scout Traps work wonders on hard carries as well :)

Stats will stack. Passives from items will not. For example, two metal jacket will give you twice the armor and shield, but two tension bow will not grant a double tension bow effect (although you will still get the additional shield pierce and attack power). As for the original question in this thread, @Skeletor is right. Upgrading a T1 item into a T2 item will not save you any money or give you more stats. On the other hand, let's say you were going to eventually build a frostburn,...

Hopefully you'll miss us, cuz we'll miss you :P

I just wanted to make sure it was clear for anyone reading this thread :)

It'll depend on how your opponents are building and how that player likes to play. crucible is almost always a must used because it grants so much additional health and give you that Relfex Block. warhorn is also a great item for koshka.

Koshka in high elo games usually only has one offensive item (aftershock), and the rest of her build is tanky.

Give her a tension bow and her merciless pursuit can deal some real damage, even while being tanky for the rest of her build. You'll still need your teammates to be the main damage dealers, but it can really help with initiating ganks.

@Bootylicious I would like to add that a player's Karma level does not influence the matchmaking system. It is meant to reward you with extra Glory for not abandoning a match.

If you need some more teammates check out @lfgVainGlory (check my sig for more) on twitter. Almost always someone on that's up for a match.

I know not everyone likes doing group queue. But it's definitely worth trying to find some regular teammates to roll with. Check out @lfgVainGlory or search through the accounts @lfgVainGlory is following to find a guild/clan. Finding just that one or two players you like to play with can really make all the difference :)
