[Chains of Harrow: Update 21.4.0]

The Hydroid changes feel like a step in the right direction but not quite there.  I played around with a few different builds and couldn't find anything that really made all of his powers click.

I like that the powers are a lot more flexible now and can even be used while in Undertow.  While I think all of his powers need further work, my single biggest complaint with the frame is: being a puddle isn't fun.  I don't think the goal of that ability should be to stay in it as long as possible.  While I like some thoughts, like removing Curative Undertow and letting Hydroid heal by draining HP from enemies...end of the day, I don't think being a Murder Puddle will ever be fun.

My favorite change in the rework is that Tidal Surge now pulls enemies along for the ride instead of just ragdolling everything.  I had fun on some survival maps using Tidal Surge to push enemies into a big group against a wall and following up with an AoE.  Enemies will still ragdoll at the end so currently you must hit a wall to keep them grouped.  This idea got me thinking about how Undertow functions.  

Currently, If something is Undertowed (if you will), as soon as Hydroid moves from their location, they are freed.  So I'm not seeing a reason to use Tidal Surge while in Undertow...I just free the people I had trapped.  And I can't stop my Tidal Surge if I'm already a puddle so I can't even aim it at a new group without re-casting Undertow.  So what if instead Undertow allowed Hydroid to Roomba-up enemies?  Using Tidal Surge and Undertow together, Hydroid could potentially suck up a bunch of enemies then dump them somewhere for his team to follow up with AoE attacks.  Hard for me to say if taking the time to group enemies up is worth it very often in a fast-paced game like Warframe, but it would give him a unique role within the game.  

Undertow, Tidal Surge a few times to collect enemies, Tidal Surge back to the group, cancel Undertow, everyone gets their murder on.  I could also see some use on a Defense mission that's going sour--as enemies cluster up on the pod, Hydroid could turn on Roomba-mode and move the enemies a safer distance to buy some time.  I'm sure some balances would be needed, like greater energy drain on Undertow as you carry more people so Hydroid couldn't just puddle all the spawns and hold them there for an extended period.

Just a thought.  Maybe not a good one, but I really want to be a Roomba.
