#Send help pls tier

• Tryndamere: 45.45% winrate, down by ~6%, pretty incredible dip in winrate given how adaptable tryndamere mains have been historically to systemic changes during the preseasons.
• Galio: 42.59% winrate, down by ~8%, its a shame he's so bad now, he would offer a lot of strength against the cheesy all damage comps we've been seeing.
