I play rexxar a lot . Xul just needs to push the waves and ignore point pretty much . Towers will fall . You get xp lead . Rexxar cant clean them fast enough . Even with the bear he is slow , and without the bear he just cant keep up . Eventually in 1 v 1 situation , he can lose his well too . Later in game rexxar is now in dangerous territory without structural defence . Ganks come easier . Rexxar is always a strong pick on Braxis . But the constant push harass , makes Rexxar have to do a lot to negate it , and can result in ganks also . Beacon control is not the only way to win the lane . You could dominate xp for your team , strengthening your teams 4 man . And forcing Rexxar further and further away from point control to clean wave . At this point , Rexxar can not clean the wave fast enough , and the range on mishas leash is not long enough , to clean wave and hold point . So therefore , Rexxar has to chose between point control and tower defence . Ive dominated chens , sitting on point . And not soaking with rexxar . Xul is basically the opposite of that .
