Seeing as my main is a 218 NT, and no one has mentioned any feedback about the 18.7 changes, I will offer my opinions.
Taken from Genele's Testlive post, I'll go over each change individually, but I'll save Nullity Sphere for last...
"Nano-Technician's Greater Nanobot Shelter and Nanobot Shielding is now a nano line that increases the caster's nano damage multiplier by 7% and 10%."
This is actually a great idea. TL5 damage is just terrible, so anything that helps at that point gets a thumbs up in my book. Losing the insane nano damage buff from Shielding kinda sucks. Doing the quest to get Shielding probably won't be on anyone's list, because it's pretty hard and only 3% more damage isn't really worth it.
"Nano-Technician's Izgimmer's Wealth is now a nano heal restoring 20.000 of the caster's nano. The line cooldown should be 2 minutes."
I see this as a good thing, and a bad thing. My NT is in the position where I have Nanobot Shielding, but not Izgimmer's Wealth, so more thoughts on that under NS.
"Nano-Technician's Forget Me! will no longer de-taunt enemies that are not in combat. The line cooldown of this nano will be 10.00 seconds."
That makes sense.
"Grid armor nukes have been removed."
I have never used any of these, so won't miss them.
"Only two team warp nano programs remain, one for self with a 5 minute cooldown and one team with 10 minute cooldown. This nano will take you to the city that is controlled by your side. Neutrals get sent to Borealis, Clanners get sent to Tir and Omnis to Rome. The caster's side doesn't affect the destination of his teammates."
Great idea.
"Nano-Technician's Nullity Sphere" and "Nullity Sphere MK II is now a damage to nano style nano programs and will no longer put the nano-technician in Defensive Focus.
Nullity Sphere: 70% of all damage gets directed to your nanopool for 15 seconds, at the end of the duration of this nano, your nano pool will be set to 0. This nano has a cooldown of 2 minutes.
Nullity Sphere MK II: Verify that 90% of all damage gets directed to your nanopool for 15 seconds, at the end of the duration of this nano, your nano pool will be set to 0. This nano has a cooldown of 1 minute. Both of these nano programs will recast Nanobot Shelter or Superior Nanobot Shelter at the end of their duration if the nano-technician has them uploaded."
Ok... There are several things wrong with this idea.
First, because Izgimmer's Wealth will no longer buff Max Nano, NT's will not have the nano pool to support this in most situations. In my case, I've got about 23,000 nano max, however my gross nano used per minute is about 38,000 just nuking (at full def).
Also, the duration is too short. Often, we need time to land NR debuffs and a DoT, or refresh absorbs, heal, etc.
Setting nanopool to 0 once NS is up... This makes the least sense out of all of the changes to Nullity Sphere. A Nano-technician with no nano is, best case scenario worthless but usually dead very quickly. So, now with several less seconds of protection, we're left completely defenseless when NS terminates. We have perk heals, etc, but that's not really a good enough reason for this.
Looking at all of these changes makes me wonder why Soldiers would still have a 75% reflect that lasts considerably longer and has (for them at least) a much better trade-off. I find it strange that a "Nano" technician would have such a crappy defensive nano, comparatively speaking.
Now that our damage has been decreased substantially, Nullity Sphere was pretty much our last trump card... So, is there anything wrong with it just being at least 90% reflect with 9 and 18 second durations(assuming 1 sec recharge time), and not draining nano pool?
