So, here's the problem with that: Of all the tanks in this game, only ONE deals physical damage. Jarvan the 4th is the only tank who would be affected by IBG, and he has his own armor shred anyways. Everyone else is magic damage, so no, that extra 150 health, won't make a huge difference. Anyone else who get's to him, is a damage dealer, and multiple damage deals or magic damage tanks won't care about that 70 extra armor, or that 150 extra health. If you're being flanked, multiple Valkyries won't exactly help, since there isn't exactly anywhere to Valkyrie too, or if there is, he doesn't need to worry about using it multiple times, because he's already safe.
