Just be aware that it completely removes your agency in a losing game. You have ZERO carry potential and ZERO manfight potential when you're running a build like this - basically your only option when you're caught alone is to escape with flight (not ideal, puts it on cooldown) or to scramble to the nearest ally.
Having said that, you can crush the absolute fuck out of teamfights. Ult grenade + Vortex Web + Kudzu Bomb + double stun will lock down often 2 or 3 enemies for 5 - 6 seconds, dealing decent spirit damage the whole way. Joining a fight in progress like this also puts you in an ideal position to use your Health Nova.
Also, your mobility is high enough as Ivy that you can gank almost on cooldown in the early-midgame. Just make sure you mic up to call out where you're going and make sure people are ready for you, co-ordination is key when you're useless on your own. And make sure you have a fucking Kudzu Bomb ready, don't fly if there's not at least one bomb up, ideally two
