Zhalo is one of the best exotics in Year 2 next to Tlaloc and the swords. Using it for an Arc burn activity is sensible and nothing more. If you don't want to use it that's your preference but I don't see how using it reduces you to being labelled a newbie, that's just weird. If it was due to not wanting to use a arc item in a burn mode then that'd be fine challenge wise, but you then tell people to use an arc sniper and Bolt Caster. Again, this makes no sense.
