Talus can do a lot of damage in a 1 vs 1 but his health relatively low. Travel is groups of two or more if possible and necessary. You can force him to use his Rune of Travel early and cut unnecessary damage from you or your team by focusing him.

Something you should always do is focus fire. If Ying has the Life Like Legendary Card, this is even more effective as the heal beam loses 30% of its healing ability, but if you spread out the damage, she will have 40% extra overall due to 2 beams.

Ying is limited to 2 stationary Illusions. If Ying wants to push up she needs to sacrifice illusions to make new ones to heal or her team will need to fall back for healing. Killing her or her Illusions gives no healing for the enemies to retreat to.

Every Champion that is on a killing streak will give their killer extra credits to spend. If you are on a streak SOMETIMES it may be worth jumping of the map before Lex can make you his retribution target and gain even more credits.
