Would you consider alternative Gem Skill level upgrade?

So many skill gem upgrade seems pointless or pushing builds from diversification to OTP builds.

I play warrior and when only see a few gems that worths even to waste a gemcutter on it.
Like we have A tier gems:
Shockwave totem - attacks faster

B tier
Boneshatter - faster attack speed? Seriously? Its a finishing move. I already made a topic that there's a massive problem with this skill. Prime mechanics are hard to execute since all my other skills can accidentally trigger stun. Unless you expect this to replace mace strike...

C tier
Shield charge shorter cooldown? That skill already have 3 second cooldown.
It just feels you want to have meaningful combat, but this skillgem just tells you to create a Shield charge 1 button build that you should spam...






Garbage:
Earthquake - does anyone even uses this skill after other skill automatically puts down jagged ground?

Shield Wall - seriously... who can put down 4 walls? Or is there a hidden build where 1 cast put down multiple walls?
Shield wall is a combo skill, not even a defensive mechanic, since any slam ability explodes it. Totem and aftershock builds can use Shield Wall, but you wont be able to put down more than 1 wall in that tremor... Its like building a card pyramid in the middle of an earthquake XD

The only time I can imagine to put down 4 wall is when there's a bossfight monologue...

Not sure if Earthshatter is the same where you can increase your spike count from 6 to 9. Who have time to even put 6 spikes down?
Btw... spike duration is 6 seconds the skill have a 0.6x aspd multiplier and its well known mace attacks are slow motion compared to other builds... So even the 6th time you cast it, the first 2 will expire...


Or is this just another warrior thing? Because when I go through other weapon skill gems they're straight damage boost or resource management improvements.

Instead of reworking how about giving you alternative paths?

Ie:
Perfect strike could have reduced fire damage conversion and increased physical.
Reason: lets say I play an armour brake warrior, so I don't even pick up extra fire nodes. I look at this skill and not sure if I even want to use it.

The garbage tiers above can have
x% chance to put down multiple sets.
Or instead of chance how about every nth cast is a guaranteed double?

Shield wall could have cast range as upgrade (boosting more with a support gem) I instinctively use Shield wall to trap enemies who wants to run away... XD

So questions:
What skill gem upgrade feels lackluster to you?

What ideas you have for upgrading gems?
