When a Protoss asks for “Strong core units” they aren’t asking for their core units to dominate the other races core units, a reliance on tech units should be necessary.
Protoss players are just asking for units that can compete at a fair level.
They balance team have really hit the nail on the head with the balance at multiple points. The prime example at the current state of the game is the Stalker.
It’s a strong core unit. It can be very powerful with blink and it’s role is very well defined but just by itself in late engagements it’s not something that is going to succeed.
This is compared to it’s past wet noodle self.
Zealots used to be good in this role too before they had their damage removed from charge.
They were pretty competent throughout the game but there was a lot of ways opponents could take care of them, in large groups their effectiveness was diminished but they were threatening to anything they could surround and heavily outnumber.
That change was primarily for the Zergling/Zealot dynamic but Protoss was never that strong in PvZ and changing this has clearly had a hugely negative impact in both pvz and pvt which is now why we have the terrible band-aid shield overcharge currently in the game.
Protoss has once again become reliant on tech units and all in’s and that is not enjoyable to either side.
Having to have stupid band-aid fixes because of the weakness of their core units before they can get out their high tech units and forced into playstyles because your core army can’t stand up to the opponents is not fun.
We have a stong balanced stalker.
We had a strong balanced Zealot.
Adepts were too strong and are currently too weak. They need a redesign. Something to breathe more life into them. They never really hit that strong, balanced level.
Sentries are utility units but they themselves feel weak. It was okay when the other Protoss units could carry their own slack but maybe a tweak to bring up their power level should be considered.
Templar are strong and balanced.
Dark templar are unique. I would say they are weak overall but they fit their role well.
