I have been trying to get better with rek'sai and have been playing my usual warrior into full tank build but I just feel really useless once laning phase is over and teamfights begin outside of making a wellplaced knockup. Is there a more efficient way to build her or is this just the nature of the champion?
Side note: It doesn't help that she gets nerfed every patch.
You could go into an offensive item after you get your warrior enchant, but you will be incredibly squishy between the 20 and 28 minute mark when your team start grouping up for 3rd dragon or the first Baron. You could always build a spectral cowl, warden's mail, or giant's belt first before getting another offensive item (I have been debating between Black Cleaver and BotRK). That extra defensive item might help you smooth out your lack of tankiness until you can finish up your weapon. The nice thing about Black Cleaver is that it is built from health stats, so it could also keep you a bit stronger when ganking lanes or in smaller team skirmishes. In all, your role in the team going into late game is really about securing objectives and the knock-up, though. You're never going to do massive amounts of damage, but a build like this could help make you feel a little more useful.
