This is a very straightforward mod. 
It provides fixes proposed in this slightly rage'y but extremaly explanatory post https://forums.obsidian.net/topic/52531-affliction-and-plague-force-power-bugs/ . 
<<I providede three files, main one chcanges only duration and ticks,
<<Vulnerable bosses subfolder increases also the DC to 121 to make it truly irresistable. 
<<TSL rebalance subfolder contains a version with increased duration but same amout of ticks (7) and (12) respectively for affliction and plague (plague at DC100), and is proposed to be used with my mod in progress TSL Tactical Combat Mod. 
However, with or without TCM, any of the files can be used. 
<<<Instalation>>> 
Drop into override oflder.
<<<Uninstalation>>>
Remove from override folder.
<<<Permissions>>>
Credit goes to the OP from obsidian forums, my files from this mod you can redistribute or put into compilations without notice, credit is always welcome. Feel free to also repackage it at will.
Cheers!

<<<TSL Tactical Combat Mod>>>

<<About>>
If you ever felt that after lvl 15 in KotOR 2, your PC and team got all powerful (Fredon's Nadd tomb being the exception) and
pazaak with Atton on (Republic Senat's rules) was more fun than slaying couple more thugs or beasts than this mod is for you.
After playing a lot of Pillars of Eternity, I realized that TSL had nearly the same potential for tactical fights but after less
than half the game you had to be counter productive to have a fight that lasts more than 4 seconds. Honestly most times I didn't
have time to use more than two force buffs because everyone was already dead. Difficulty changes only enemy damage output so it
makes things harder but enemies still drop like flies. This mod aims (and will aim, definitely not finished) to correct that.
 
<<Changes>>
Files changed are classes.2da, autobalance.2da and k_sp1_force.ncs; autobalance has significantly increased NPC's health, slightly buffed 
saving throws, set NPC's level to be equal to PC. Classes.2da doubled gained health (on lvlup) by PC and team and raised
force point gain (on lvlup) by 50%. !!!Because of game mechanics, increased health points and force poins gain doesnt work 
retroactively, meaning you'll have to start a new game (as even KSE cannot change your vitality poins directly), this will 
probably NOT be "fixed" in future releases. Enemy HP and other changes will apply once you enter new area after installing.
 
<<Compatibility>>
This mod works with TSLRCM and is being tested and developed to work with it. If you don't have TSLRCM instaled changes might
not be appropriate for your playthrough. This mod should work with any other mod that doesn't change those files: 
Classes.2da, Autobalance.2da, k_sp1_force.ncs
ADITIONAL FILE: dialog.tlk included in this download goes to the main folder and not override. 
It should be comatible with the TSl RCM game but any mod that changes dialog.tlk might not be compatible and will require testing.
My file includes modified force powers descriptions to account for extended duration.
 
<<Install>>
Drop files to Override (who doesn't like that? )
 Dialog.tlk goes to main install folder and make sure to back it up lest you have to reinstall main game and mods.
<<Uninstall>>
Well, this is going to be difficult...
 
(remove Classes.2da, Autobalance.2da and k_sp1_force.ncs from Override folder, replace dialog.tlk with backed up version if you used it)
 
<<Future changes>>
-A lot more testing and figuring out the perfect balance
-If you have an idea for more changes or would like to help with this leave a comment or PM me.
 
All the best!
