Storm basically confirms that in 0.8.6, LeFH 18 French premium arty gets moved from T4 to T5, accuracy gets nerfed from 0,49 to 0,73, shell price gets doubled and the shell velocity is reduced.
What this means by the way: ALL 105mm German derp guns will have the velocity reduced, not just this arty.
Either way, Storm states that the "characteristics" of LeFH will stay practically unchanged, because due to the "new coordinate system" (SS: what the hell is that?), it won't fit tier 4 anymore. According to Storm, the shell price is a "system change" and the profitability of this vehicle won't be affected.
And about the arty accuracy "nerf" .... Storm might tell today :) I'll make a separate post about this later, but it's absolutely clear the arty accuracy will get a serious overhaul.
Edit: the "coordinate system" is a translation fail from my side, after consultation with Edrard (thank you!), we came to conclusion that by this, Storm means the new battletier spread.
As for the artillery accuracy overhaul, it will be published in 5 days officially.
