in a party where we can rush a clash in one single aa of nekro, one nekro is enough, also in a boss fight where we need nekro shield is only needed in a certain period (e.g. 5s reflect on third boss), having two nekros can disrupt the intended timing,

but the trend is we also use nekro for running from mobs in pve... having another 1 as a backup is preferred... i agree that in the 5s period where nekro shield can be deployed we can die in large pulls, but if we only have 1, we will be shieldless in the next 17 seconds... sooo, for me 2 nekros is still better :P, as my playstyle is very defensive
