I've found out that if in each groups of 12 that htey will last longer if you have 6 zealots, 6 dragoons, 2dts, and 2 archons, though expensive if you mass these groups you'll just go on a rampage. Note: this is only from personal experience.
Also, you would be better of with only having a single unit type per group. I mean, Archons and Dragoons in the same group? Nah.
Idk, archons + Dragoons could be good, Archons high shields and dmg, while the dragoons take the range picking of units left and right while the archons take dmg. It would be really good with a sheild regen close by!
^ Yeah, but that's the the kind of job you'd send Zealots to do, which is much cheaper and more effective than Archons.
Most important is bases and unit pumping, and teching. It doesn't matter if you can micro 6 dragoons when the enemy is attacking with 12 Battlecruisers.
yeah but the archons are effective when taking out heavy fortifications, the archons are more concentrated on in battle saving many others, because one timeI had a lot of dragoons still left when the last archon was dead (but I do actually have atleast six gateways so pumping out these guys aren't a problem... for me i mean) p.s. also with an arbiter this is very deadly. and I meant 4 dragoons and zealots
It depends on the situation. Every protoss player requires units where it can provide a reasonable amount of firepower, durable and relatively cheap eg. Zealots. Unless required, the Archon should really be a support unit or fight along side zealots. Archon's strength lies on attacking masses of infantry and it's cost probably justifies that it shouldn't be placed as a front line unit by itself.
Pure unit control groups are better in my opinion, much easier to dance dragoons and zealot charge with a pure zealot and a pure dragoon group than 2 of 6 each.
like in every balanced game, it depends on your enemys units. Against Zerg A lot of archons and HT's are necesarry, Archons are nearly never used against Terran though. But generally a lot of dragons/zealots are needed, the x:y again depending on your oppononts units (dragons against lurkers, zealots against zergling - not the other way around). Edit: Im voting for pure unit controlgroups, ofc...
