2.1 Primary- and secondary objectives as a healer
Your primary objective as a healer is to keep your party in good shape, not as black and white as keeping them alive. Staying alive is an individual job, rather than yours. Keeping your party in good shape involves:
- Having sufficient HP at the right time
- Is free of most, if not all, negative status effects
- Being prepared for sure-kill attacks unless properly mitigated
Your secondary objective would be to make the encounter as forgiving as possible, although opinions on this may vary. Making an encounter more forgiving involves handling mechanics or contributing with damage. For most encounters, especially when progressing, the dps checks is one of the main causes for failures. Assuming your primary objective is achieved till the dps check fails. By taking duties handling mechanics from other players would improve the overal damage output. Alternatively you could help contribute with some damage as a healer.
