well. my opinion is: " bring back the Tumor " [since it is killed, the REDMODE of Spawners start in the begin and in europe is that a massiv non playable game] - The Penalty in the first minute would be to hard maybe... there is [nothing you can do vs penalty. (play nice friendly, and if kill time is over, you can attack)]
In One Way, you also lose your Unique Units, because they are Spawner.
Quote " Some suggestions:
.1. Zerg overlords to start from 500 minerals (from 600)
.2. The overlord cost increase to 100 minerals (from 125) "
wow this is really Crazy buff. 1 & 2 is not combination able.
in oneway it is 540or 550 @start. 525* was to high buff.. [well i play europe]
the problem of normal hex is the penalty ... you did a good move, and get killes by penalty.

Infestable Missile (Raket) Tower
Can Produce "Infested Marine"
a free Unit is what you want

?
The Effect of selfklick, kills a bit the random attack style. but he got a new funny unit. glhf.
250 Damage +1 is the problem of OP Marine + 600 Shatter.
if Veteran only has that... Terran would be okay.
but now comes a another problem, Veteran is more OP as Marine._____________________
i think Terran ||| Balance is okay.
1vs1 = zerg Win
2vs2 = zerg/terran win
x vs 6 = Ion or Terran win____________________
What I did with your Idea [post]
so update for you in Zerg Hex One Way
StartSupply
Cheaper.

~not really did, because i know the system was horrorfull op with 500. [OneWay* has
lowered Supply Anforderungen (
14 for Mineraler| Big Units massiv better in
Supply optimated there)
*roach 6 _ primals 6 _ Ultralisk 10_ Brutalisk 27.5 or 28 (Baneling -5 ; Ravator -2 ; Torralisk -10 ; Roach Infected - 9; Beastling 12-14 [-3-.1]
Some Units Stronger /cheaper ?
damn i forget to make the Hellion and goliath cheaper - one momennt -4--12mins i want. <---- Reduced to 45-51Minerals [was like 55 before]
the damn Veteran Marine so crazy strong.... how much was that cost 50-55minerals? normal.? now 44minerals. [+4]

reality, if you buff zerg with StartEco [more spawner(slowling spawner) | Mineraler] (nothing really happens in the game, because the Supply needs so much Mineral, that every effect kills)(it is just a better feeling (better eco)). But it helps vs 1 aggressiv player, because your eco will not hit that hard [mineralers not hitable before big spine]. (losing spawner looks not so cost/Kill intensiv (eco killing)]

you are correct to lower the StartSupply of Standart Hex into 500. Totally Agree!
