Work out your job in this draft and keep the balance between farming and fighting: if you are farming a timing item, ignore the pointless fights and the tier 1 tower defence, and do not give in to your team when the fight is lost before it starts.
You went into a pointless fight because the team pushed you into it — you lost the timing of your key item, when you could have farmed 1–2 more minutes and taken that fight with your power spike.
