One season is very long, 10-11 weeks being between 2-3 months. A new player starting Warframe is intended to use the Nightwave system to buy the essentials for starting out, meaning MR fodder weapons, Vauban, Aura mods which are essential to mod capacity and Orokin Catalysts/Reactors for weapons strong enough to take into Nightwave challenges.
Looking at the shop alone, a newbie needs Nitain, potatoes, Vauban and weapon BPs for mastery.
One rank reward of wolf creds give you 50.
Vauban requires 75.
One Potato requires 75, but if it's a Catalyst (Blue), one is given as a rank reward.
One weapon BP requires 50, of which there are 9, but Heat Sword can be skipped since it's a quest reward so you have 8.
Nitain requires 15 for a set of 5.
Auras require 20.
Assuming you skip potatoes & Nitain while only using Corrosive Projection (one of the most important in the game), you need:
75 + 8(50) + 20
= 495 wolf creds MINIMUM.
Assuming a newbie can reach rank 30, he only gets wolf creds from rank 3, 6,12,16, 20 and 24...
that's 6 x 50 wolf creds = 300 wolf creds.
He's still missing another 195 wolf creds so if he starts dipping into prestige, for a rate of 15 a rank he needs a minimum of 195/15 = R13 Prestige.
This is in no way possible for a newbie. A veteran with enough time to grind, sure, but NOT a newbie.
If a newbie is capable of attaining rank 24, he should have several elite weeklies under his belt and would not require any of the weapon BPs to use as real weapons, because he would have sortie-viable weapons and frames (or at least capable of lasting through one without burning all revives).
It would be far faster to tell a newbie to just farm plat off of trade chat to get anything he needs, because there's no way I want to subject some MR5 dude to hydrolysts and 60 minutes of kuva survival just because he needs some essentials.
The only way I can fix this without changing Nightwave too much is to either move most of the rep into dailies or massively discount the auras, weapon BPs and potatoes.
TL;DR: You literally do not have enough wolf creds in the system to buy all essentials within a single season without prestige. Please lower the cost of items or increase rep gain.
