Ture, I saw a clan yesterday score 18B points from training T5 troops. 

I think if you do the maths of the points gained per level of troop against the cost of the troop it works out that training T1 troops is the best option.

The major downside to this is rather than to 10 lots of training at T5 or T6 level you end up doing 200 lots of training for the same points but have saved a lot on resources (or gold if you're flash).

Many Jarls save up a lot of boosts and resources then go for training as much of their highest level troop as possible.

We've chatted about this before on the post here: https://plarium.com/forum/en/vikings-war-of-clans/ideas-and-suggestions/112167_stop-these-winning-by-training-and-sh-boosts----/

Its probable that this has all been thought through, and its to cover various aspects of the game that have become more predictable, as well as getting players to go , cough up for the latest updates.
