Without addressing OPs points one by one (as I believe this is about the 10th similar topic about NG being weak, etc. in the current meta), I'd pinpoint one major issue only with the faction, and mostly their bronzes - and that is their lack of internal synergy. NG has a lot of interesting archetypes, however these are typically not functioning well when mixed withon a deck. You have soldiers (clearly benefiting from other soldiers mostly), assimilate cards, deck manipulation cards, status cards, poison package, etc - yet, if you check their mechanics, usually they either require non-trivial setup, or just plain suffer when moved outside from their own archetype.
Looking at a faction that received a lot of hate nowadays, SK, or even NR for example, and examining their bronze package, we can spot two obvious things:
- they have (especially SK) solid options without any serious conditions to produce those sweet 7 for 4 and 8 for 5 provision cards;
- their bronze package has excellent internal synergy, allowing for great interchangeability, flexible ordering, and sometimes even a chance to compete with other faction's golds.
I really believe the key to address several factions "bronze unit" problem is to look into these small synergies between cards. The negative examples are NG, SC (porbably even in a worse state than NG tbh) and in multiple cases SY.
While the formula for success in case of SK is obviously the ease-of-use dmg/self dmg mechanic, the lack of such "finesse" is impacting some of the factions heavily.
As a quick conclusion, buffing a card by 1 or playing with provisions etc. while can be beneficial, it won't solve the core problem, the one being that cards need to benefit from / synergize with each other.
