The 600-versus-175 attack range gap means Senna can contest the wave from outside Rell’s reach. The burden is on Rell: Senna has no reason to walk into an even fight.
Rell and Senna overlap on mixed damage, so itemisation converges rather than splits. Rell carries 620 base health to Senna’s 530, and 30 armour to 25. That 5-point armour gap favours Rell in the first all-in. Late-game bases read 2388 health / 98 armour for Rell and 2043 / 93 for Senna.
