Offices & Hospitality (Staff)

Offices & Hospitality right now is useless as moral now used.

We could change it to train staff (CD TD DR)

First of all staring age of new staff should start lower at market not 50 - 55 for 18 - 19 level. Around 25 - 30 would be ideal.
Staff could have trainable Skill 1 - 20 and will give as the star rating. Skill 1 = level 1. 18 level staff will be 4.5 stars for a 20 player etc.
CD could have extra 1-10 skill for strength and weakness
     Option to change strength and weakness. 
     Strength could be as it is now to give 1 to 10 points extra to design
     Weakness could scale with 2 points and give from minus 30 to minus 10 from the best (42-43 Design points)
Training for skill according to player level as drivers are and my suggestion is that will take 10 days minimum and cost of token according to cost of buildings as they are now.
Changing strength and weakness for CD would reset his/her strength and weakness Points. if we change strength the strength will go at level 1 and for that change training would need minimum 15 days (Token cost for 15 days).

Just a thought.
Thanks in advance;)

I just read a suggestion relating offices and hospitality being a direct relation to improvement in sponsorship deals in some fashion.

I think your suggestion is also fantastic; but would be done through the tech centre. Leave the hiring side as it is though; allow the training of skill, experience gained by races with the team. I’m also for your idea of development to maximise the strength effect and minimise the weakness effect.

For the TD, increase in skill, means closer to ideal setups (force us to figure it out after each TD level up) but also; like KERS and DRS, attach a pit crew to the TD, so when the TD is leveled up, you can level up your pit crew as well. Even introduce strengths and maybe weaknesses to the TD like Pit Crew, Setup, Pre-Race Management (tyre/duel data in practice) and race day management (tyre/fuel data real-time during the race)
