Dude it was a loss that Exoria was built on TVP luckily i could make it fully stable in less than 2 weeks, you have no clue how far i went from your engine, so
You say i using your engine, feels like im fixing your mess because the server was based on it. [I won't change whole engine and give up on such a simple challenge]
You say i stagnate/mimic your structure (Stop fantasizing yourself haha) my server today relies on the TFS 1.4.2 structure in your engine nothing else :
QueryManager by SSD (Full of shit Rollbacks without crash, saving/loading problems : useless in production good for testing server which makes it more useless, that you will think its fine but actually its not)
FollowAttack // FollowCreature (Completely messed up till i had to correct many issues about it for myself)
Gamebeat (completely messed up)
Skills Multiplier (Completely Messed up)
BlockHit & Formulas (30% Correct, 70% Messed up)
AttackModes? (Messed up in multiple aspects that you probably didn't notice while mimicing realOTS instead truly reversing the code using IDE tool)
Paralyze // Invisible & Conditions in general (Completely not correct)
SpawnRate (Completely messed up but that wasn't big one yet its game destructive.)
..etc (I can mention more 20 Issue that had to be resolved in your Divine Engine that you don't have any idea how much it went far from all of your solutions and now relies on mine)
NPCs Issues : (That you are clearly aware of

)
So You are trying to keep a good face instead getting hold of your shit.
So Almightly Ezzz Why Promise77 by Ascendia had to fall multiple times ? (TVP Issues)
Why Promise77 had to struggle with multiple releases? (Because you didn't give it the care it requires as a customer for you you literally say its solved and the say issue occurs in less than 24 hours so you made it seem relying on useless developers, which actually was the case. )
Almighty Ezzz : Why you didn't use TVP if its the fully Perfected Engine after 10 years of effort? maybe i can tell you why if you don't know.
Because : it had too many flaws to be relied on with RL OT Project.
So if i rely on your engine i rely on the TFS 1.4.2 aspect of it, i had to go through every single change you made over tfs 1.4.2 and rewrite it because the logic was poor & code seemed like (Error & Trail Result) instead being (Logic based structure)
Edit: I lost time, effort to make a corrupted engine flawless and free of bugs, capable of holding a world enough to grow, i wish it didn't rely on your engine or whatever you sold for your clients 1k USD thats a loss to pay 1k usd for.
Thank you for reading.
Another Edit: Proof-case of my capability in Making Poor engines useable and solid is Evolisca, its Engine is OTX2 [TFS0.4 Based] and its flawless.
