Honestly this is why we will not see one for a while, with options already to purchase those who are very tempted will pay them, what is actually being requested is a decrease in value of Zeta to facilitate lower spenders to purchase.
LSB indeed have put new bottlenecks in game. Zeta is the obvious one but ‘competitive’ mods were also challenging to acquire at the rate of LSB acceleration. In part it’s fine as it provides chance to prioritise as this is an important economy game at its source. The more important aspect to consider it’s quicker to get zeta’s than decent mods. Even if you purchase zeta’s for all LSB squads ready, are they actually ready are there stats where they need to be to be functional. Have you got the missing characters not in the bundle. If not there is plenty of time to back fill zetas from the game.
