Kalista, Worst Ult Ever

Ok, I'm not the type to ever post or participate in the forums. I generally just let Riot and the community do their thing and go with the flow. However, What in the name of God prompted the designers to come up with such an Ult as hers?! I'm a fan of team synergy and all that. I like being able to click on thresh's lantern and tele to him. Kalista's Ult is however the most annoying thing I have ever encountered. I don't think it needs to be completely removed but it does need to be revamped. I want a way to opt out of and remove the Oathsworn junk. I hate having her override whatever i'm trying to do by using her ult. Imo all you've done, by not giving us a way to break the link, is given trolls a tool with which to further annoy and irritate the rest of us and even encouraged the regular player to become a troll. I've asked questions of several Kalista players, in the games i've played with her, trying to find out if there is a way to decline or break the link or refuse the ult. When i express my dislike of having some other player take control of my champ i'm generally met with them responding with "lols" and then making it a point to keep using it on me. I know I can't be the only person out there feeling this way, so hopefully this will get some notice and prompt you Rioters to make a change here ASAP
