Don't worry about it. hmm. Well from what I've seen, compared to Tryndamere and Olaf, Irelia doesn't do as much physical damage. Poppy, Zilean, and Karma will end up dealing a LOT of magic damage, which could force your opponents to stack magic resistance. This would hurt their damage a lot, so it's important that you have some way of countering this, and the way to counter it is by getting someone that deals a lot of physical damage, to force them to spend gold on armor or health as well. I'm not entirely sure, I just think Irelia's physical damage might not be enough to do that.
