PBE Karma analysis
got some changes in the PBE which are refreshing to say the least.
Read more here if you don't know about it yet: http://www.surrenderat20.net/2015/05/513-pbe-update.html
Passive - the passive change is HUGE. It allows Karma to use her mantra more often. And we know how deadly she was in URF mode. PBE testings have proven that it is now much easier to cast double (or triple) mantra Q later in the game.
W - castable on jungle monsters! Also seems to reduce mantra cooldown when used on jungle monsters. I'm not sure whether this is a bug or not.
Mantra W - this is a big hit to solo lane Karma. The healing portion is less efficient on 1v1 situations and it is only useful in team fight situations and taking jungle objectives. The change is quite drastic and I wouldn't be surprised if Riot decided to buff W damage to compensate the loss of damage on the mantra version. In the PBE it also doesn't seem to scale with mantra ranks at all. We'll see if this gets addressed or not. Hopefully yes.
Mantra W now increases the root duration by 0.75/1/1.25/1.5 seconds based on mantra rank and also heals for 20% missing health when you cast it and when the root is applied. Bonus damage is still removed.
E - Cooldown reduced from 10 sec to 10/9/8/7/6 seconds based on rank. With 40% cdr that is a 3.6 second cooldown on a 4 second lasting shield. That is a huge buff for any Karma player. The reduction of shield value is compensated by mantra effect. Also mana cost reduction, YAY!
Mantra E - Damage removal is understandable since it wasn't the main source of damage on Karma's kit anyways. The extra shielding will be handy when dealing with high burst champions. A nerf to her late game wave clearing and it doesn't proc her passive anymore.
#Mantra W
Many people have been upset about the change which reduces solo lane Karma's sustain/safety. Personally I believe the buffs to the passive and mantra E compensates for the loss of burst healing (which was over the top to begin with). Karma is still able to gain a good amount of health from mantra W during a jungler's visit.
Karma has the tools to keep herself safe during the laning phase even without mantra W self healing. Proper positioning and use of shield will reveal the good Karma players from the bad ones. Mage Karma will survive if you adjust your playstyle to the new changes.
Karma is now able to root a target for 3.5 seconds at level 16! The change is still somewhat a nerf to solo lane Karma's trading potential since the bonus damage has been removed from mantra. You are still able to gain a lot of health at low health and guarantee your escape due to increased root duration.
Shield bombing
Some Karma players might say that shield bombing is the core of Karma. When she was first released she was indeed a proper shield bomber. However after the rework the shield bombing got overruled by mantra Q and people soon realized that mantra E was just useful on rare occasions as a damaging tool. I'm glad the damage portion of the shield got removed and added as additional shielding to better define Karma as THE shielder.
HOWEVER!
I'm disappointed that such an interesting support ability has now been removed from the league. I will be looking forward to seeing a new champion who can utilize this power even better than Karma could.
#Overall
Karma becomes more suited for the support role but is still able to go to a solo lane. Top lane Karma will most likely vanish since she'll need aid from the jungler more often. Baiting tactics become more harder to pull off due to mantra W changes. Some minor damage buffs to W and scaling to mantra W would be nice.
