In definitive we agree on the main problem :
- zergs doesn t take enought risks
- decisive mid game for Terrans
I m not fan (but i like it) of your idea cause the mecanism of spreading creep is already in this shape. in my mind, spawning tumors with a queen and 'tumor multiplicity' is biased choice - As i show in the graph above, there is an over concentration of queens spawning ability at the start of the game. It s different from an overlapping abbility, it s just like these two spells aren t made to work together (...).
SC2 works in macro management, and adding an upgrade like you said can smooth the start of the mid game, smoothing the step in-between Z massively spwan tumors with queen ability and the 'multiplicity spell'.. however if we are used to melt upgrades one by one in order to make a 'build', i m not fan of the idea of a new 'forced upgrade' (as mandatory to win the game - there is already 'overlord speed'...)
My tought about promote the cleaning tumors action by a terran or a protoss wasn t so drastic, i have only forget some details :
In killing the last tumor, borrowed tentacle of tumor will bleed and heal his wound until the next to last tumor has scared over.. Then, as the process is curing, the tumor hasn t to be revealed, it only become visible 'x' seconds after killing the 'active/multiplicative' one, and then become not visible after it stop bleeding. This delay is done allowing Zerg to defend.
To be honest, your solution is great cause as you said :
Zerg should have to use their queens in more forward positions early game instead of essentially laying a few tumors down and focusing purely on larvae spawns for 60 more secs.
My solution make me happy cause it brings something more to opponents, it promotes players to settle in an area more easily, it promotes to siege before creep lines while the pro player (mainly terran..) actually has to move (and kill ?) into the nest / swarm / base.. To me it s attractive cause i enjoy a new mecanism without changing any parameters in Zerg race (vision, delay, mana cost, ...).
Maybe it s time to rethink again...
PS : Go further with my idea :
+ Show Spoiler +
Then we could have the opportunity to settle some bunkers (with an updated upgrade, separatly from 'neosteel frame' which will also, reduce building time, plus adding 2 cargo space, adding some hit points..). Actually, banelings can easily wipe out a bunker lines whatever you have 4 or 6 cargo space... All marines are too close (crowded) together so it doesn t matter.
It could open a different way to the mid game for struggling against creep, it could demand to zerg players more decision army movement, it offers a turning back to the terran.

All tumors looks like as one unit, as a network...

Test with decreasing vision of tumors (from 10 to 7)... Note you can t spwan new tumors in fog of war.
