Some of you cite how you have trouble with dead of night on Artanis and I may like to remedy this.
You say you go tempest, and this is basically your first problem. Not only are tempests not the optimal choice versus masses of units, but they are not the best dps choice either. In dead of night there is a very large amount of units to deal with, being the infested, which is typical for a crowd control scenario. Zealots are pseudo crowd control in that they have AoE with their upgrades, using them will benefit you in dealing with the map. If im not mistaken zealots are pretty much artanis’ highest dps unit as well, meaning faster clearing of buildings. Ontop of all of this, the infested have many marine like units which shoot up, making tempests weaker pick as opposed to a ground to antiground unit like a zealot or immortal. Tempests also take time to tech into and have air upgrade priority which on Artanis doesnt include carriers, so tempests are your only upgraded through cyber core option for antiground damage, resulting in a slower to acquire antiground army. All of this makes tempests a suboptimal pick on this map.
Some of you also state reavers as your pick and while they sport good AoE they are best at killing masses of units and not so much buildings. They suffer from the same fate tempests do in that they are slow to tech up and dont offer the best benefit for this map.
While immortals are ok on this map, I dont think they are necessary for Artanis and the best comp for dead of night specifically is somewhere between zealot dragoon and zealot archon.
